Cannot login to Desktop after Stretch upgrade

Postby g1annos » 2017-06-18 22:59

Today I upgraded my system to Debian Stretch following the official guide. During the process I saw it would remove fglrx graphics driver, but I thought everything would be alright. After restarting the system, I get
Code: Select all
(EE) Fatal error:
(EE) no screens found
.....
.....
.....
xinit: giving up
xinit: unable to connect to server
xinit: server error


Any ideas? Would be nice if I could avoid installing from scratch.

I read that fglrx is no more supported at Stretch. My GPU is an Ati Radeon 5750. I've the item source driver installed.

Firstly try revert to the "old" xorg.conf before fglrx was installed. If you used `aticonfig` to create a new xorg.conf, it would have created a backup of xorg.conf as xorg.conf.original-0. If that backup file is empty then you can just delete the current xorg.conf.

Also check /etc/modprobe.d/ for configurations that blacklist the open source driver "radeon".

You might also would like to reinstall mesa-related packages.

Fglrx itself as a dead object is no longer installable atop the current kernel and Xorg.

Do you mean a login loop or no login screen at all?

No login screen at all. The is not a xorg.conf file. Isn't there a generic driver that simply works? Just to work with gui rather than writing from my tablet?

You might look here: https://wiki.debian.org/Xorg
Scroll down to: What if I do not have an xorg config file?

Do you have /etc/X11/xorg.conf.original-0 ?

Yes, you should be using "radeon" after dropping "fglrx". Check if it's blacklisted:
Code: Select all
grep -R 'radeon' /etc/modprobe.d/

I solved it: The generic driver for AMD GPUs is in the package firmware-amd-graphics, which is in the contrib non-free repository.

Installing this package solves the problem. Thank you all!
