Description Pierre Bonneau 2021-06-15 07:11:34 CEST

Description of problem:
When you run mageia-prime-install, a config file is generating and stored in the /etc/X11 folder for later use. That file is also used if you execute mageia-prime-install -p even if the content should be different.

Version-Release number of selected component (if applicable):
0.4 64 bits

How reproducible:
Execute mageia-prime-install
reboot to nvidia config
#nvidia card used
Execute mageia-prime-uninstall
reboot to intel config
#intel card used
execute mageia-prime-install -p
#the wrong file is used.
reboot
#nvidia card used
execute mageia-prime-uninstall
reboot to intel mode
#intel card used
remove the file xorg.conf.nvidiaprime.preserve
execute mageia-prime-install -p
#intel card used with nvidia offloading

it's working as expected.

Hi, as far as I read, if /etc/X11/xorg.conf was previously set by mageia-prime, the offloading doesn't work, you need to remove "xorg.conf.nvidiaprime.preserve" even after do 'mageia-prime-uninstall'...

Assigning to Giuseppe.

Comment 2 Giuseppe Ghibò 2021-06-15 13:25:47 CEST

After having unconfigured try the offload configuration adding the -f option (so mageia-prime-install -f -p).

By default mageia-prime-uninstall preserves the working xorg.conf file after
unconfiguring. In this way a subsequent call to mageia-prime-install can re-use
such file without having to regenerate one. The '-f' option permits to override this behaviour and thus create always a fresh xorg.conf, without having to re-use the preserved one.

Hello,

Thank you for your quick feedback.

I still think it would be nice for the tool to detect that the saved configuration is not accurate. It's quite difficult to know what the system is doing, and it took me 3 days to figure out that issue.

I'm going to update the mageia wiki with your answer.

Also, if I might, it would be nice when starting the tool with a command line to start by a comment line that explain in plain English what will be done.

Ex : 
mageia-prime-install -p -f
#Installing Discret card in offloading mode.
#Forcing generation of configuration file
