I'm trying to write a script to convert a file and copy the converted text to the clipboard so I can paste it into a website. This question got me started. My script contains, in part:
xsel -ib < txt/"$BASE".txt
After running that command, I can paste into my text editor (Geany) no problem. However, when I paste into Chromium, nothing gets pasted; Chromium seems to think the clipboard is empty. What's going on?
I'm packaging an app I wrote in Python 3 which uses:
from gi.repository import AppIndicator3
As I'm listing the dependencies, I have been unable to determine what package contains AppIndicator3. I guessed python-appindicator, but looking at that package it appears that it's for Python 2, not Python 3.
Which package should I depend on?
I'm writing a small Python 3 app which uses AppIndicator3 to place an icon in the top bar, and then change that icon in response to user actions. Simple, right? Because the app is small, it needs to run from its source directory without any kind of installation.
The problem is that AppIndicator3.set_icon() requires a str with an icon name, not a path to said icon.
How can I persuade AppIndicator3 to let me give it either a filename or a Pixbuf? Alternatively, how can I add my icon directory to the icon name search path? (I tried AppIndicator3.set_icon_theme_path(), but my icon names are still unrecognized.
I recently upgraded from 14.04 Trusty to 16.04 Xenial. Prior to the upgrade, I used the caffeine-plus indicator icon to tell the my laptop when it could sleep. The mode I normally used was to have Caffeine enabled so the computer would only sleep/suspend when the lid was closed. However, there were occasions when I wanted to be able to let the idle timer have its intended effect.
Since the upgrade, Caffeine doesn't appear to do anything anymore. I can leave my computer with a long-running process, deliberately keeping the lid open, only to come back to find it sleeping and the process unfinished.
How can I get the previous behavior back? Note that I'm looking for a toggle, not a permanent change. As a toggle, it should have a visual indication as to whether it's enabled or not. An indicator icon would be great.
The searching I did prior to asking this question turned up either: a) old (outdated) posts about how to use Caffeine, or b) permanently disabling sleep to work around various hardware bugs. My question is simply about restoring the functionality I had in 14.04, a topic I didn't find addressed.
After upgrading from 14.04 to 16.04, I have a number of issues with LibreOffice. See this screenshot:
Regarding the circled numbers on the screenshot:
Some interface elements, such as these tabs, the font color is nearly invisible.
The icons are difficult to see against the dark background. The default icons were much worse, but changing to Tango icons improved, but didn't fix, the problem.
The automatic font color is worse than before. See number 4.
Text using the automatic font color appears maroon. Previously, it was nearly black, which caused its own issues. This, though, is just ridiculous.
I'm using the default Ambiance theme. How can I fix these issues?
A bug report contains a solution for issue 1: Launch LibreOffice as follows, possibly via a wrapper script:
SAL_USE_VCLPLUGIN=gtk soffice
This does not solve the other issues I pointed out.
One of my most popular answers is instructions on how to repair grub. Over time, others have contributed bug fixes to the answer. A recent comment, though, made me wonder if it works on newer UEFI hardware.

I get a "cannot find EFI directory" at step 7 and cannot boot. Any ideas?
All my hardware is older, pre-UEFI hardware. So my question is this: Are my instructions, particularly step 7, applicable to UEFI hardware? If not, what changes need to be made?
Yesterday while I was watching a YouTube video the sound started glitching. There are two kinds of glitches:
I originally blamed Adobe Flash. However, killing it didn't fix anything. Then I noticed that PulseAudio was consuming a lot of audio during the glitches. So, I killed it. No dice. I rebooted. No dice. I decided to test another program, so I tried Rhythmbox. The same problem occurred, but with less frequency.
What's going on here?

I've lately been having an issue with my root filesystem becoming readonly. It happens some amount of time after boot. I don't know exactly when it happens, as I don't usually notice it until something such as suspending the computer or printing fails. It seems to be fairly random. Since most of my system is on that partition, I can't re-mount it without rebooting.
After this happens, the system runs a fsck. Sometimes it prompts to fix problems; other times it apparently finds none.
To troubleshoot, I've searched through the logs but found nothing relevant. This might be due in part to not knowing when the actual errors took place.
The filesystem is apparently good to begin with, as when fsck runs its fixes it doesn't report any errors.
I've scanned the disk with SpinRite. A while ago, SpinRite found and recovered from some bad sectors on the hard drive. I ran a level 4 scan (a thorough scan) after this probem appeared, but SpinRite found nothing.
The SMART data reports that the disk is OK with 63 bad sectors. The number of bad sectors hasn't changed recently.
I realize that the disk isn't in the best of conditions, and I have complete backups in case of catastrophic failure. Yet the lack of errors in the logs, combined with SpinRite's test results and the unchanged SMART data makes me think that this problem has some cause other than disk failure.
Other than disk failure, what could cause my symptoms?
In trying to solve a problem with Windows, a tool I was using deleted some of my partitions. I used TestDisk to recover my partitions.
While it managed to recover all my data partitions, it couldn't recover my swap partition. Normally, that wouldn't be a big deal, since it's easy to create another swap partition. In this case, though, it also didn't find my extended partition, so all my recovered partitions are primary partitions, instead of logical partitions. Now, I can't create any more.
I want to re-create the layout shown in my pre-event fstab:

Clearly, I don't want to delete any data to do this. Are there any tools that are capable of this? It seems that if I could write the partition table at a low level, I'd be able to accomplish this. What do you recommend?
By the way, I use an encrypted home directory (that's $HOME, not /home), and previously my swap was encrypted. I don't know how encrypted swap is set up.
Until recently, Firefox on my machine used the standard Unity global menu. However, recently the menu is no longer global and, strangely, is centered. See this screenshot:
firefox-globalmenu is installed, the extension is enabled on the Add-ons page, and all other programs work as expected. Furthermore, the menu is as expected in a guest session.
Here are the extensions I have enabled:
How can I get the global menu back?
(This is Ubuntu Oneiric [11.10] with Firefox 9.0.1.)
I restarted in safe mode (all add-ons disabled). Here's what I saw (note that the only change is that the menubar is no longer centered):
Next, I renamed ~/.mozilla to try a fresh profile. The problem was cured. However, I consider this to be an unacceptable solution since I have a lot of settings, add-ons, stored data, etc., etc. that would be lost with a fresh profile, only some of which is covered by Firefox Sync. A solution that involves lost data is no solution.
For years, I've had the following in my sudoers file:
scott ALL=NOPASSWD: ALL
For those who don't know, this prevents sudo and friends (gksudo, etc.) from asking for a password. However, over the years, more and more stuff that once used sudo has been switched to using PolicyKit.
I'm looking for an equivalent configuration for PolicyKit, such that it'll never ask me for my password.
For those who don't like my request, let me say this: I understand the reasons for the default configuration, and they are sound. I also understand the risks inherent in the configuration I want to make. Nevertheless, it's the way I want to set up my system. Those who don't fully understand the above shouldn't attempt what I'm attempting.
For a long time, I've had my keyboard configured to use the layout currently known as "English (international AltGr dead keys)." I like this layout because without any modifier keys, it's identical to the US English keyboard, but when I hold Right Alt I can get accented letters and other characters not available on a standard US English keyboard.
In Oneiric, however, the layout is messed up. Right Alt+N produces "ñ" as expected. And another method works: Right Alt+`, E produces "è", also as expected. But there's no way to type "é", which is probably the accented letter I type the most. I expect Right Alt+A, E to do the trick. But instead of a dead key for the acute accent, it uses a method for combining characters to create the hybrid "́e". This hybrid looks like the proper "é" in some settings, but it isn't the same character and doesn't always work. (For example, in the text input box as I type this, it looks the same as the proper character, but when displayed on the site for all so see, it looks very wrong--at least on my machine.) Ditto for all other characters with an acute accent, though some are available directly as pre-composed characters: For example, Right Alt+I yields "í".
How can I change the acute accent on the A key to a proper dead key? Perhaps the more general version of this is: How can I tweak my keyboard layout?
I just tested this on my other machine, also running Oneiric, but upgraded from previous versions. I have no problems with the second machine. The problem machine was a fresh install of Oneiric, but I kept my old $HOME when I did the fresh install.
Even if an answer doesn't address my specific examples, I would still accept it if it provided enough detail for me to find the layout and tweak it according to my needs.
After working through the information gained through Jim C's and Chascon's helpful replies, I've learned something new: The problem isn't with the layout itself, but with the fact that the selected layout isn't being applied. When I look at the definition in /usr/share/X11/xkb/symbols/us of the layout I've been running for a long time, I found that the definition doesn't match what I get when I type. In addition, the keyboard layout dialog that's supposed to show the current layout looks different from the way the layout is defined in the file I mentioned, and matches what actually happens when I type.
Following Jim C's suggestion, I created a new layout in /usr/share/X11/xkb/symbols/us containing some modifications to the layout I want. I can select my layout from the keyboard properties, and I can use in on the console following Chascon's post, but the layout I get when typing is unchanged.
Apparently, there's a different layout defined somewhere that's overriding what I've set. Where is that layout hiding?
This problem occurs in Unity (3D and 2D), but I was able to get the correct layout set in Xfce.
In case it's relevant, this problem has occurred since I installed Oneiric fresh on this machine (though I preserved my $HOME). I don't recall whether this problem occurred before the reinstall.
Also, in case it's relevant, I also run iBus so I can type Korean. I have a few difficulties with iBus, but I doubt they're related.
On several machines that I've upgraded from Natty to Oneiric, I get an error every boot (one for every NTFS partition):
Serious errors were found while checking the disk drive for /windows/c.
Press I to ignore, S to skip mounting, or M for manual recovery
Following the suggestion in this answer, I ran fsck from the manual recovery shell. I got this output:
fsck from util-linux 2.19.1
fsck: fsck.ntfs: not found
fsck: Error 2 while executing fsck.ntfs for /dev/sda1
I can't find fsck.ntfs, and command-not-found doesn't help either. How can I make this error go away?
By the way, I've tried booting into Windows (XP) several times, thinking that Windows would repair the filesystems. But apparently Windows thinks the filesysystems are just fine. And it's odd that all NTFS filesystems are affected.
Also, I can work around this problem by dropping to a recovery shell and issuing mount -a, but for my coworkers' sakes I need unattended boot.
I can change the background image that Unity Greeter displays, but regardless of the image I choose, it's overlaid with a grid of dots. The dots look OK on the default background, but they look horrible on the background I want to use. How can I get rid of them?
Since Oneiric, if I leave my machine (HP Mini 110 netbook) unattended and it goes into power-save mode, the backlight gets disabled. How can I turn it back on? Note that the keyboard backlight controls (Fn+F4 and Fn+F3) don't have any effect in this situation.
I've already filed a bug, but filing a bug doesn't fix my problem. I tried this workaround posted in this bug report dealing with Acer laptops:
sudo setpci -s 00:02.0 F4.B=0
However, if anything, that command makes things worse. In the general case, I can see a little bit if I'm in a dark room with a flashlight aimed just so. But after running setpci I can't see anything. And I find the setpci documentation to be utterly incomprehensible, so I don't know whether I need to tweak my command somehow or whether I'm completely barking up the wrong tree.
Update:
I've found a workaround: I'm now booting with the kernel parameter acpi=off. This disables power management, which prevents the machine from going into power saving mode and thus failing to come back up correctly. Of course, not having power management means that I can't use suspend or do anything to manage power other than powering it off (even then, I have to manually use the power switch). Also, it prevents me from using Unity 3D or Gnome Shell, forcing me into Unity 2C or Gnome Classic. So, I'd really like to be able to stop using this hack.
Update 2: Midway through Oneiric's run, a kernel update fixed this issue. But this question is still relevant as a general procedure for working around showstopper kernel regressions.
I'm trying to change the icon for application/x-hwp files. I've added the icons to the proper places, and checked it with assoGiate (after reading this thread). It shows that my desired icon is associated with the file type. Nevertheless, Nautilus is still showing the old icon. How can I make Nautilus show the correct icon?
I use the USA International keyboard layout. Every time I log in, the USA layout gets added to my list of layouts, which causes the keyboard layout indicator to be displayed. How can I stop the USA layout from being added?
Additional info: I'm running Natty. Until recently, I had all four layout slots filled. Recently I changed from SCIM to iBus. With this change, I no longer need multiple layouts since iBus better handles my needs. So, I don't want both indicators (iBus and Keyboard layout) showing up.
I just upgraded my netbook thus: Lucid -> Maverick -> Natty. (I skipped Maverick other than as an upgrade step due to issues with Unity.)
Now, I seem to be stuck with something that looks like Emerald but apparently isn't (see note below). Compiz is running, as is gtk-window-decorator, but my title bars aren't following Ubuntu's theme. I was using the Ambiance theme with no problems until the upgrade to Natty.
Here's a screenshot:
How can I get the default theme?
Note: I never installed Emerald, and as far as I can tell it isn't installed. There's no running process containing the string emerald. So I'm not sure where gtk-window-decorator is getting its configuration from.
Following htorque's very reasonable suggestion to run unity --reset made matters worse. Now, after logging out/in, most of my theme-related stuff is gone entirely and can't be changed (clicking on the themes in the dialog changes the title bar/scrollbar color but nothing else). Here's a screenshot of the current situation:
Possible Duplicates:
Is there a way to turn off “auto-maximize”?
How to keep programs from launching maximized? 11.04
On a small netbook screen, it's useful to have windows maximized by default. However, on two separate machines with full-sized screens, Unity doesn't seem to realize that always opening browser windows maximized is just annoying.
How can I teach Unity the error of its ways? On a full-sized screen, I don't want Unity to auto-maximize any window, unless I happen to configure it to do so for a particular window (which is unlikely).
(By the way, I'm running Natty.)
I have a set of duties I must schedule employees for. The duties recur weekly over a two-month period. There are a number of constraints that define a good schedule. (See below for examples.) In the past, I've made the schedule by hand, but doing it by hand is time-consuming and virtually guarantees a buggy schedule.
I'm looking for software that will make the schedule for me. I've tried TaskJuggler, but I'm not sure whether it's even capable of doing what I want (the documentation is unhelpful and the folks on the mailing list merely tell me to read the documentation--which I've done without conclusive results).
Can anybody recommend something?
Here's an example schedule. Note that since this one was handmade, it contains an error or two.
Here are some of my constraints:
