System: Gnome unstable / B550 Board / MSI RX5500 8GB / Ryzen 7 3700X /

There’s an nvidia-fake-powerd package in the AUR now, built from those instructions.
I think it should go without saying, but use at your own discretion! Used with 495xx drivers.
Nvidia GT730 Geforce not longer working after update (unstable) 07.11.2021.
Error: “Driver doesnot support your GT730”
SOLUTION:
in GRUB press “E” and add to bootoptions: 3 nomodeset
Boot (F10) => login prompt => login and type:
sudo mhwd -r pci $(mhwd -li |grep 'video-' | awk '{print $1}')
sudo mhwd -a pci free 0300
reboot…
(Nvidia-driver replaced by opensource-driver)
Or install the new Nvidia driver package made for the occasion (The previous driver)?
mhwd -l

I uninstalled and reinstalled linux514, and the folder and its contents are back.
All set 5.10.78 is fine on ThinkPad T60
I’m getting a strange update issue that sounds like it would be system-breaking, as of just now. I declined, of course. What should I do? Here’s what I saw in my terminal:

Refresh your mirrors and/or wait until your mirror syncs, you need the xorg-server 21.1.1-2 packages first. Sorry, they came in slightly out of order. 
Neither uninstall nor downgrade anything.
Yup, waiting worked. Thanks for the info! I hope nobody accepted that prompt while it was active.
After the last update (Plasma 5.23.3) Octopi fails to start with the following error:
octopi: error while loading shared libraries: libqtermwidget5.so.0: cannot open shared object file: No such file or directory
UPD: sudo ln -s /lib/libqtermwidget5.so.1.0.0 /lib/libqtermwidget5.so.0 worked for now. I know it’s a workaround but I don’t care much as I use Octopi only for ez browsing of packages anyway.
Install it from the AUR for now, apparently no one here is interesting in updating it. 
Gnome 41 finally came.
I did the update in TTY, rebooted normally.
Smooth and seamless.
Latest xorg-server update to 21.1.1-2 can cause some “fun” with scaling on plasma. I had to force the old default of 96dpi to reduce huge icons and fonts to proper size again. Plasma scaling was set to 100% at all times.
There’s also this thread in the arch forums.
Here nvidia-390xx driver is not starting after xorg-server update.
Apparently the change in xorg-server will be reverted in 21.1.2 next week:
Arch itself might be opting to revert in it’s package sooner:

The update of an old Nvidia driver just now fails with all 3 of pacman, yay, and pamac. Here’s the output from my terminal. What should I do?

Temporarily ignore the update for mhwd-nvidia-470xx. They’re only database files and it appears you don’t have the NVIDIA 470 driver installed, anyway. I’ll look at it tomorrow.
EDIT: Fixed with mhwd-nvidia-470xx 470.86-2.
Thanks! I updated and it worked just fine.
Since last Update (09.November2021)
GNOME boots into Wayland, although “X-11” is choosen (= target wanted).
Automatic login, entry “Gnome on xorg” selected.
Manual login into x-org works, if switched from “Gnome on xorg” to “Gnome”
and back to “Gnome on xorg”. Does not survive reboot…
Simple solution:
edit: /etc/gdm/custom and uncheck “WaylandEnable=false”
NO really a solution, only workaround.
Whats wrong with the Tigers??
