I'm working with a cast-off Intel server, and when I go to the Boot Menu after POST, there's an entry there BOOT0006. It does not appear in the BIOS/Settings which I access with F2.
How do I remove that bogus entry?
I have Windows Subsystem for Linux, but I don't know which version I have, and many things won't work in version 1. How do I check my version?
I've generated multiple 18.04.2 and 18.04.3 LiveUSBs with persistence, but have not been able to permanently remove original apps (in particular, Amazon, Mines, Solitaire, and Thunderbird) by selecting to delete them from the GNOME GUI.
Also, I launched Software and Updates, set the Download source (to mirror.uoregon.edu), added Community-maintained free and open source software (universe), then installed two apps with:
sudo apt install stress stress-ng
After rebooting, stress and stress-ng were gone; Amazon, Thunderbird, and games were back.
The LiveUSBs were generated by the Pendrive.com Unversal USB Installer (1.9.8.2) and Unetbootin 6.6.1 (as well as other apps no longer supported).
How may I do this post hoc, without the Custom Build process, perhaps by flushing the changes to casper-rw?
I downloaded the current 18.04.2 Desktop ISO, checksummed it, and ran LiLi from Windows 10 to generate a LiveUSB. In Step 4, I selected the Virtualization feature shown at the LiLi link (see 'No reboot required').
I can boot from the LiveUSB and run Bionic AOK, but the virtualization feature fails when I go to the VirtualBox folder on the LiveUSB and launch
Virtualize_This_Key.exe
A black-on-clear dialog box appears when I launch that, asking me not to close VirtualBox.
I do have Local Admin rights on my Windows 10 Pro machines (tried on several, both RS4 and RS5).
I left a request for support on 2019-07-31 on the LiLi website; echo answereth not, no response.
Virtualization was enabled in the BIOS/firmware setup; I had been running Hyper-V AK on one of these boxen before I uninstalled it in advance of this test. All virtualization methods are now uninstalled.
Anyone use this feature? Any special tips to make it work on a supported Ubuntu? Or is this app pining for the fjords?
How do I set fBreader (already installed with sudo apt-get install fbreader) to be the default epub and mobi file reader in Xubuntu 18.04? When I double click a .mobi or .epub file, fbReader does not open, and instead I am asked what kind of a file it is.
How do I set FBReader as the default mobi ebook reader? is specific to non-Xubuntu flavors and does not work with Xubuntu. Unable to find another relevant suggestion relevant to Xubuntu.
Just downloaded and installed the ISO of Ubuntu 18.04 LTS onto a flash drive. Does that have persistence? If not, how can I generate a Live USB with persistence?
The Menu Bar of MATE in 16.04 text reads Applications Places System
How may I change that to read Apps GoTo Syst to release more panel space for other uses?
I am seeking a panel object of some kind which would put a flashing light on the panel for Lubuntu 14.04 LTS, for I have an elderly small screen laptop which has no drive activity lamp.
Lots of such for Windows, not finding it for GNOME/LXDE except for System Monitor, which is overkill for my taste. Just a flashing light on the panel, that's all I care for.
My Lubuntu 12.04.1 install of VPN Unlimited's client failed about a month after its first use, and their online docs do NOT match the Linux version they provide. I asked for help with these details on 11/06:
"In the past week, your client often won't show me which VPN server I am connecting through and will not allow me to change server locations. Today, I get a complete failure to connect. The DETAILS button shows me VPN Connection is not connected, but when I try to connect, it fails again. Despite what's in your FAQ, there's no instructions provided by the app, and no Manual option. Selecting another server location does not solve the problem.
I downloaded the client from vpnunlimitedapp.com/downloadlinux and reinstalled it using Gdebi after a complete removal with Synaptic Package Manager. Gdebi reported all dependencies were satisfied when it reinstalled. It still fails to connect. How may I troubleshoot this? What logs may I send you? Platform: Linux Ubuntu 12.04 32 bit compiler little-endian, App version: 2.3"
On 11/07, they replied: "Hello, JohnI have forwarded your issue to our developers. They will assist as soon as possible. We apologize for any inconvenience."
Which logs and other info could I be looking through to try to solve this on my own?
Once I launch the client, it says it is connected, but I am not able to connect to the Internet with any app, and can't ping out to anywhere.
I can connect to any server only if the VPN Unlimted client is disabled.
There are no log files to be found in /tmp/VPN Unlimited/, nor is there any directory named VPN Unlimited underneath /tmp
uname -m returns the result: i686
With a ThinkPad X61 and Lubuntu 14.04.1, wireless fails to connect but Ethernet is AOK. Multiple SSIDs are seen, in tests at multiple locations, but entering their keys do not enable connection. Open access points also fail. Same key works well on other Thinkpad. MAC address filtering is not on in the gateway (SMC D3GNV). Problem replicated with a different distro booted from flashdrive.

Xubuntu has a nice way of showing network data flow in the panel; put the Network Monitor in the panel and choose the network interface.
I know that Gnome has a similar feature in its System Monitor http://www.thegeekstuff.com/2009/11/ubuntu-tips-graphical-monitoring-for-processes-memory-load-average-and-disk-usage/ - but is there an Xfce equivalent?
In Xubuntu 13.10, many apps, such as Bluefish, Calibre and Firefox, when launched put their window off-kilter, high and to the right, so the top of the window's frame is concealed. Pressing {Alt-Enter} x to revert to ordinary sizing is vexing. For programs which don't have size and position settings, how may I fix the location and size for opening windows, so the buttons at the top of the window are not hidden?
Tried using settings manager to click on Window Manager Tweaks, select the Placement tab, and slide the bar under "Minimum size of windows to trigger smart placement:" all the way to the right. This did not help.
It may be relevant that Panel 0 is at the top, and Panel 1 is at the left. Metacity is not in use. It happens whether or not Display Compositing is enabled in Settings | Windows Manager Tweaks | Compositor.

Have a Samsung 840 SSD in a Thinkpad R60i running Xubuntu 13.04 /w 3GB usable RAM. Provisioned it with 20% free space and enabled TRIM, and it was fast as greased lightning to start, but four months later it takes three times longer to boot. Only down to 30% free in my ext3 file system and only installed 500MB of apps since install.
I have seen Slow Samsung 830 SSD! and did update the firmware before install.
This Ars Technica article reveals the likelihood that CPU based random number generators "RDRAND" and "Padlock" have been crafted with NSA input to benefit NSA code cracking.
Do the current Ubuntu distros utilize those routines on machines with Intel and VIA CPUs?
If so, can those generators be bypassed by installing other code?
A search on "random number" did not reveal either, and since privacy is important to many, I do believe this is of general interest and not an obscure issue.
After searching here, I found no direct answer to:
Is it practical to put swap on a USB Flash drive? I do not yet know if the teeny-tiny flash drive (Fit CZ33 ) I wish to use runs at high-speed (480 Mbps), full-speed (12 Mbps), or low-speed (1.5 Mbps), but am checking w/ SanDisk.
My intent is to reduce writes on the SSD for drive longevity; if the external flashdrive fails, I throw it away and get another.
Why? Because I just changed my ThinkPad R60 9459AT8 over to a Samsung SSD after maxing out the RAM at 3GB, set up trim after repartitioning with 20% free, removed swap, set swappiness to 0 and otherwise tuned up Xubuntu 13.10 for SSD. However, since it's not practical for me to add a mechanical HDD, I'd like to move the swap over to a Flashdrive which will always stay in the left side USB2 socket, for I'dather wear out a $12 flashdrive instead of a $180 SSD.
Why? Sometimes, I lose my WiFi connection until I reboot, plus rarely see slowdown, and I'd like to see if having swap again would help. I do watch a system monitor always in a panel and never exceed 30% free memory use, but would like to have swap without putting in on the SSD.
Yea, or nay?
And, does the size of the flashdrive make any difference: 8GB, 16GB or 32GB?
How do I report a problem with the Ubuntu Guide website?
http://ubuntuguide.org/images/UbuntuGuideSaucyPt1.epub is linked from http://ubuntuguide.org/wiki/Ubuntu_Saucy_Repositories under 'eBook Version' above the list of contents at top of page,. However, that link is 404'd. Also tried http://ubuntuguide.org/images/UbuntuGuideSaucy.epub which also fails.
So, where do we report Fail at ubuntuguide.org? I see nowhere there to so do.
I have also tried, twice on separate days, to register there, but never get the confirmation email.
Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM. Last week with 13.04, I had 4GB of RAM (which matches the BIOS) and this week I have 3GB available. Inquiring minds want to know. Details follow:

I have seen on older (ca. 2004) RHEL systems a screensaver, xlock, with a twisting and morphing picture of J. R. "Bob" Dobbs. An extensive search of screensavers available for Ubuntu has not provided revelation. Does any SubGenius out there know where I may find it for the current Lubuntu?
Where do I expect to find it? Well, every screensaver app available via Synaptic and Ubuntu Software Center has been checked, to no avail, including xscreensaver. I have also done an extensive search for it via multiple search engines, not merely looking at the first screen in a Google Search. That's why I am asking here.
How might I import that app from Slackware's repository into Lubuntu?
I've always installed Ubuntu desktop (many versions and flavors) with a decent internet connection, but now I find myself preparing for my first-ever server install (13.04 chosen for the need of Grizzly), in a place without broadband. I therefore wish to prepare for installing everything from media, which I would download before I wander off to the Boonies.
How can I download all the files I would need for a complete Open Stack install, on a single machine, before I leave the blue blanket of my broadband connection?
Once downloaded and a basic install performed, would I install additional packages needed by apt after revising /etc/apt/sources.lst to point to where the Big Pile o' Files be, or would I manually install each with dpkg, or, on the Gripping Hand, do it in a way I do not yet recognize?
