Slow cold starts on Ubuntu are a known issue with Canonical's Snap application format, as acknowledged in official blog posts like https://ubuntu.com/blog/improving-firefox-snap-performance-part-3 If you can install a Flatpak or .deb package of Firefox, you should regain that performance. Found a post recommending a "Mozilla Team" PPA at https://ubuntuhandbook.org/index.php/2022/04/install-firefox-deb-ubunt… but I last used Ubuntu 15 years ago, so I can't speak to the specific recommendations therein.

I have hibernate after following this: https://ubuntuhandbook.org/index.php/2021/08/enable-hibernate-ubuntu-2… But I don't have full disk encryption so I don't know how it works with it.

I made the switch this morning by following this: https://ubuntuhandbook.org/index.php/2022/04/pipewire-replace-pulseaud… So far the only anecdotes I have are (a) everything seems to be working and (b) don't forget to reboot after installation.

While I love the fact that there is a native RDP solution in Gnome 42 using Ubuntu[1], I did not manage to get it working... hopefully they fix it soon. Besides including encrypted ZFS support in the installer that makes a pretty awesome release :-) [1] https://ubuntuhandbook.org/index.php/2022/04/ubuntu-22-04-remote-deskt…

I don't know about any LTS versions, but 21.04 has pipewire in the standard repo. I expect PW to be in the 22.04 LTS based on that, but I don't expect it to be the default any time soon. This PPA [0] works fine for me in 21.04 to get the latest version. Support for the PPA seems to go back to Bionic, so you should be able to use it on recent LTS versions of Ubuntu as well. The only annoying part of the whole process is that the migration requires running a bunch of commands to stop and mask PulseAudio and to enable pipewire. This guide [1] worked great for me.

I've not heard of pipewire. Need to check this out because I'd love for my truly wireless earphones to be able to seamlessly switch modes on Ubuntu. I use a wired headset for work calls I need to be on quickly because it's pretty flawless, but the tether is more than a little annoying. EDIT: It took me 5 minutes after reading the comment above to replace pulseaudio with pipewire on Ubuntu 20.04, now I have access to my earphones' high quality codecs too right from the Ubuntu sound control panel! I used this[0] then this[1] [0] https://ubuntuhandbook.org/index.php/2021/05/install-latest-pipewire-p… [1] https://ubuntuhandbook.org/index.php/2021/05/enable-pipewire-audio-ser… - I only followed steps 1 and 4 and audio was switched instantly, earphones already paired. Now I have AAC, SBC, SBC-XQ... EDIT2: Switching to/from my earphones and from 1 bud to 2 buds appears flawless so far, even for the Spotify desktop for Linux app which usually requires a `pulseaudio -k` to send the audio out of the right device usually, even if it's correctly selected in sound settings. EDIT3: Don't forget to mask pulseaudio (yellow box, second link) or pulseaudio will load on reboot and break things, no amount of systemctl disable will stop it without masking. EDIT4: Linked site has different theme on mobile so yellow box in EDIT3 isn't yellow.

>If NVIDIA can't be asked to fully support their hardware on Linux, the least they can do is release some documentation so the Nouveau devs don't need to grope in the dark. I don't disagree in principle, but they've killed it, releasing information to make it work might be a problem for them, and since this thing is no longer supported adding compatibility for older devices isn't a high priority for them. It worked poorly on many windows machine, it's effectively still doesn't work on Windows 10 [0] and it's been effectively killed since 2014. [0]https://forums.geforce.com/default/topic/860554/geforce-mobile-gpus/wi… It's also worth noting that NVIDIA couldn't get the darn thing to work on Linux, it's also worth noting that AMD also had/has similar issues with PowerXpress on non-Iris based Intel CPUs, it does somewhat work well on AMD's own CPU's with integrated graphics and it's more modern "APUs". >Do you have a source for this? Source for what? under Iris Intel the CPU handles the switching between GPUs not that it works that well, but it doesn't work well on most OSs other than windows mostly due to how the display driver infrastructure is setup and how the composition manager works (even on OSX you still likely to want to use gpu-switch than rely on the OS). If you want to blame some one blame the OS tbh, if OSX and Linux had proper user mode display drivers like WDDM, had modern display drivers like WDDM and actually had a composition…

This might help? https://ubuntuhandbook.org/index.php/2021/11/time-limits-for-kids-ubun… I use a physical kitchen eggtimer to signal to my son it's time for a break. I joke that the eggtimer is compatible with all operating systems, has less setup and maintenance than any (let's be honest) linux application and generally forces me to get out of my chair to turn it off. It's simple, but it works.

I'm not sure what you meant by "stock in distros", but I hope you don't mean it comes installed and configured out of the box on all distros, as that is emphatically not the case: https://askubuntu.com/questions/1399464/cant-install-pipewire-on-ubunt… https://linuxconfig.org/how-to-install-pipewire-on-ubuntu-linux https://ubuntuhandbook.org/index.php/2022/04/pipewire-replace-pulseaud…

The stock save icon in Ubuntu hasn't been a floppy disk for years. Here it is:http://ubuntuhandbook.org/wp-content/uploads/2014/03/firefox-desktop-f…

> Either you're being hyperbolic about the length of time or this is simply untrue. I am not hyperbolic, X11 has this Xv API, video players generally use it since early 2000s (as that was only reasonable way to even scale video to fullscreen with contemporary computers). Browsers - well, that is a different issue. I do not think Firefox uses it and have no idea about Chromium. > Part of it was that Linux did not have hardware acceleration in browsers, which is where I spent most of my time (especially for video playback, such as YouTube). Linux also have hardware decoding acceleration API (even multiple ones - historic XvMC, NVidia-specific VDPAU and current mainstream VA-API), their support in software is more spotty than basic Xv API (AFAIK MPlayer implemented VDPAU but not VA-API, MPV required for some time explicit option to use VA-API and i have no idea about VLC). Firefox got support just recently: https://ubuntuhandbook.org/index.php/2021/08/enable-hardware-video-acc… I would generally suggest to view web video such as YouTube in MPV video player using its youtube-dl integration. It is much better experience than playing video in Firefox.

I have this kicking around from some experiments a month or two ago: sudo apt-get update sudo apt-get install build-essential linux-image-extra-virtual sudo reboot echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf cat > /etc/modprobe.d/blacklist-nouveau.conf blacklist nouveau blacklist lbm-nouveau options nouveau modeset=0 alias nouveau off alias lbm-nouveau off <Ctrl+D> sudo update-initramfs -u sudo reboot sudo apt-get install linux-headers-$(uname -r) wget http://uk.download.nvidia.com/XFree86/Linux-x86_64/346.35/NVIDIA-Linux… chmod +x NVIDIA-Linux-x86_64-346.35.run sudo ./NVIDIA-Linux-x86_64-346.35.run nvidia-smi -q | less This is obviously not production-ready, and is heavily cribbed from online (I couldn't quickly re-find where) but is good enough if you just want to play.
