Ok, this issue is caused by audio powersaving and deleting 'load-module module-suspend-on-idle' in /etc/pulse/default.pa and system.pa and restarting pulseaudio disables audio powersaving and fixes...

I have some weird interference in speakers. Well, the interference itself is not weird at all - usual AC mains humming, and looks like it picks up some radio station too, but weirdly only when...

Note also that chromium does support hardware video acceleration on linux while firefox doesn't and is much more demanding to CPU.

Open in in libreoffice. It converts pdfs to draw, so it will be awkward, but you'll get what you want.

This is for notebooks. For UPS you have to install UPS management software e.g. nut if your UPS is supported https://networkupstools.org/ddl/Eaton/ Or check if Eaton has proprietary linux software.

My suggestions would be to try with a clean profile and provide the url. Also you stand a much better chance of getting an answer if you ask this question in a firefox forum.

I also have this problem and it seems to be related to older AMD CPUs - mine is AMD Phenom(tm) II X4 975. Probably compiled using modern CPU instruction set unsupported by older CPUs.

ps until...

There is cygwin (https://cygwin.com/) and there is also WSL on windows 10, both provide fairly robust linux environments on windows including rsync. You can even run ubuntu in WSL.

Yes, logs you posted plainly state that it *was* suspending and then something went wrong. I don't see how you reached the conclusion that video drivers are to blame, for me this openrazer-daemon...

This is not entirely true, rooted android can do this e.g. using blex (magisk module). No root - no luck.

There are two kinds of programs: some e.g. libreoffice run a single or linked processes for all open windows while some e.g. kate run independent processes for each window. What you are seeing might...

My first guess would be a hardware issue. Run xev to check

I think you are on the wrong track: unless something is lost in translation this message doesn't indicate any sort file or filesystem corruption, it means that your application/pdf file type is...

Make sure that you are using the same versions of firefox and firefox extensions, ensure that all settings are the same by copying firefox profile and that both systems have the same fonts installed.

Does the path '/SDB1_Mountpoint/Ubuntu_Mate_18.04//home/andy/.mozilla/firefox/9r99csdk.default/' exist? Looks like it doesn't, and cp cannot create folders as needed, you should use " mkdir -p...

touch cannot read filenames from stdin

Define automated, and keep in mind that automated does not mean mind reading. You want to touch a list of files, so you have to pass this list to a program somehow, and one way of doing it by listing...

The screenshot looks ok, it means that the problem is between the video card and the monitor. Such things usually happen when using analogue VGA cable and can be corrected by zooming and aligning the...

Usually program writes errors, warning and other messages to console, in order to see them you should start it either from a terminal or from a script redirecting stderr to a log file '<program> >>...

No idea. I don't go with this newfangled stuff, adding '0 6 * * * /usr/sbin/ntpdate pool.ntp.org>>/var/log/ntpdate.log 2>&1' to crontab works now just as fine as20 years...

Yes, it can. Install mdadm package and run 'mdadm --assemble --scan'. If everything is ok run 'mdadm --detail --scan >> /etc/mdadm/mdadm.conf' and edit the last ARRAY line in mdadm.conf you've just...

It may be EFI-related. Make sure secure boot is off in BIOS (UEFI) settings, upgrade BIOS to the latest version. If 'ubuntu' appears in BIOS boot targets, select it as primary.

Hidden directories usually contain application settings and temporary files. If you copy them, applications will work exactly as they did on the old system, if you don't, settings will be reset to...

First of all, gtk-launch wouldn't be of much help here as it starts .desktop files from a single location /usr/share/applications, not from an arbitrary path. In KDE you can associate "kioclient exec...

xset -dpms
xset s 0 0
