Back in the Unity days, there was a Compiz setting where you could force inactive windows to dim. I frequently work with two monitors and multiple windows open and it regularly happens that I start typing in the wrong window.
I already tried changing the colour of the titlebar, but it doesn't seem to help me much.
Is there a way to dim inactive windows while letting them remain legible?
I'm using Gnome as my Desktop Environment.
The Additional drivers dialog is showing this:
Does this mean that my system won't connect to Wireless AC networks? Is there a way around this?

I'm trying to make Flatpak Libreoffice the default app for opening files in Thunderbird.
At the moment, Thunderbird (also a flatpak) is using System Handler as default. I tried changing it but cannot find where the libreoffice executable is on my system.
I found the libreoffice .desktop files in /var/lib/flatpak/exports/share/applications but Thunderbird doesn't seem to recognise the app?
I tried to make Python 3 the default Python version by running:
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
This broke Python 2 programs, so I tried reversing the process and finally I tried:
sudo update-alternatives --install /usr/bin/python python2.7 /usr/bin/python2.7 10
which made python2.7 the default Python version but Software Updater doesn't run and running aptdcon in a terminal gives:
bash: /usr/bin/aptdcon: /usr/bin/python3: bad interpreter: No such file or directory
I tried reinstalling Python 3 but got:
Errors were encountered while processing:
/var/cache/apt/archives/python3_3.4.0-0ubuntu2_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
How do I revert this mess?
I have big 100+ page tif files and would like to be able to split it at a specified page.
there are excellent tools for doing this with pdfs. I'm looking for something similar for tif images, both GUI and command line solutions.
Many times I end up with many Nautilus windows open. I would like to reduce clutter by joining them into one window with different tabs.
Is there a(n easy) way?
In Raring, everytime I connect to the network, Cups installs all the printers in the network automatically, some more than once.
Furthermore, I connect a USB printer to the laptop every now and then. Even though the printer is configured already, another printer is added to the list.
I wish to disable this feature and allow only manual installation of printers. How do I go about it?
Today I received an update notification for three updates but update manager doesn't say what updates are they.
Does anyone have a clue what this is about? How am I to check what is to be updated?
I have a folder with subfolders in it and many libreoffice documents (.odt).
I need to find in which one there's a particular phrase.
I tried grep -ir "search phrase here" . but it only found the search phrase in an xml file.
Is there a way to search in documents that are not plain text files?
I used tesseract to produce the special html to use with hocr2pdf starting from a muti-page tif.
I tried using hoc2pdf to produce a "sandwich pdf" (image + hidden text layer).
Hocr2pdf produces a one page pdf with all the pages superimposed.
Is there a way to solve this problem or an alternative solution?
I have a series of TIF files and would like to merge them into a Single TIF file
How do I do that?
I have two folders having in theory an identical folder structure and the same files.
I wish to check for differences between the two copies in the two folders. I can run diff folder1/file1 folder2/file1 one by one but this is time consuming.
Is there a way to identify which are the files which differ in the two folders? If not is there at least a way to compare the contents of a folder with the contents of the second folder?
I need to use two different Windows applications, one works well with Wine 1.4 but not on Wine 1.5 and the other application works well with the later version but not with the former.
Is there a way to have both versions of Wine installed, specifying which application should run with which Wine version?
Everyone who was used to Windows can imagine what symlinks are and how they're used. On the other hand, the hard link concept is foreign to Windows (am I correct?).
I would like to know what are the typical uses to hard links in Linux. I've already seen different posts describing the difference in how they work. What I'm asking is what are some typical situations when a user would be better off using hard links instead of symlinks?
A few days ago I noticed that after I login in, the top panel and the dash took a bit more time to load and I noticed more disc activity than usual.
I thought that it might have been caused by some update or by the installation of pdftk. So I removed pdftk but the "problem" persists.
Is there a way to know what is using the disc (read/write operations) on startup?
If it were at a later time, I would use iotop but I can only launch iotop after I get control of the desktop.
I'm on Ubuntu 12.10 amd64.
I took a look at the logs and in the Xorg.0.log file I found the following lines:
[ 36.230] (II) XKB: reuse xkmfile /var/lib/xkb/server-ED81635D9DABCAA502951B920776FB5895D92DC0.xkm

Could this be the problematic step?
I needed to run convert with a lot of images at the same time. The command took quite a while but this doesn't bother me.
The issue is that this command rendered my computer unusable while the command was running (for about 15 minutes).
So is it possible to throttle the command by limiting resources (processor and memory) to the command, directly from the command line? This can only work if I add something to the same line before pressing Enter because once I start the process the computer slows so much that it is impossible for example to switch to "System monitor" and reduce priority.
I managed to run top and sudo iotop >iotop.txt while doing one of these convert operations. (The iotop.txt file produced is difficult to read)
Results of top:

Furthermore, even after the process ends, the computer does not return to the previous performance. I found a way around this by running sudo swapoff -a followed by sudo swapon -a
I installed a mainline kernel for testing purposes. I would like to set grub to boot from the older kernel by default.
I know I can set the GRUB_DEFAULT=0 setting for the first page of grub but how do I set it to boot by default from one kernel in the second page (Advanced page)?
I would prefer doing this without installing other software (ex. grub-customizer).

How do I set Windows to boot as the default in the boot loader?

In the past I had a printer that had the booklet format option that would print the document two pages at a time ordered in a way that folding the whole printout would produce a booklet, half the size of the paper which could be stapled in the middle.
My current printer does not support this feature. I would like to use some utility or script to convert an A4 pdf to an A5 booklet one.
I found this page but I'm getting an error : pdfjam ERROR: can't find pdflatex!
How do I get past this issue? Does anybody know of any other solution?

I regularly delete old kernels leaving only the latest two entries using Synaptic.
I'm using Precise. However in my Grub "previous Linux version" menu there are quite a few entries labelled 2.6.8. I cannot find these linux-images in Synaptic.

Please help with removing the old and inexistent kernels from Grub.
I regularly annotate pdf files and unfortunately there is no good linux pdf reader that supports decent annotations. Evince has a very rudimentary and buggy annotation feature. So I'm stuck using a Windows viewer through wine.
This works pretty well but, when I simply right-click a file (in this case a pdf), properties, open with and selected Foxit Reader, the Unity Launcher icon remained the wine icon instead of the application icon.
Has anyone set a wine program as the default program for any file?
Any ideas?
