Description Bit Twister 2013-11-09 08:26:54 CET
Description of problem:

no console video with 3.12.0-desktop-2.mga4 kernel at runlevel 3 with fglrx
video driver during log in.

Kernel command line: BOOT_IMAGE=mga4_64_a3 root=LABEL=cauldron nokmsboot vga=794

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


How reproducible: Always. 
Happens on systems with fglrx driver. Did not happen on radeon video system.


Steps to Reproduce:
1. install latest updates
2. reboot


Guessing new fglrx driver compile needed for 3.12.0-desktop-2.mga4

Workaround:
Enter your log in id/pw and startx even though there is no characters on the screen.
KDE will then come up.



Reproducible: 

Steps to Reproduce:
Comment 1 Bit Twister 2013-11-09 13:25:13 CET
Installation of fglrx-kernel-desktop-latest-13.250.18-11.mga4.nonfree.x86_64.rpm
and dkms modules did not fix the problem.

Severity: normal => major

Comment 2 Thomas Backlund 2013-11-09 13:52:26 CET
try to reconfigure graphic setup through mcc, as it's probably still set to use the free driver

CC: (none) => tmb

I would hope an upgrade/update would not change whatever driver was set by the user. :(

Example: I have fglrx set as driver, new fglrx kernel/driver release should not change it to radeon or vesa.

In this case it was fglrx before the update. Quick run through mcc, graphic setup, reboot did nothing towards fixing the problem.

I saw no errors in journalctl.

Falling back to desktop 3.12.0-1.mga4 boot will give console video.

In normal situation (as in stable releases) it should not happend.

What happend here was you updated before the matching fglrx prebuilt driver was available (due to a forgotten commit by me, so the sheduled build failed), so the the needed kernel module was not available, so drakx tries to switch back to a config according to available modules...

I think it would be nice if a successful kernel build would kickoff a fglrx build or at least send the submitter an email to commit a fglrx build.

> so drakx tries to switch back to a config according to available modules

Hmmm, in that case I would have thought I would have had video. I'll go ahead and configure radeon/vesa/reboot to see if I can get any video.
Comment 6 Bit Twister 2013-11-09 14:41:43 CET
Changing to Xorg/vesa did not provide console video.  :(
Guessing problem needs to be assigned to kernel or dracut maybe since kde/startx is working.
Comment 7 Thomas Backlund 2013-11-09 14:45:34 CET
And if you reconfigure it for fglrx again ?

Yes as soon as I read comment 2. 

FYI, I have reconfigured back to fglrx, rebooted, no video, startx, su - root, dracut -f, reboot, no video.
Comment 9 Bit Twister 2013-11-16 02:09:46 CET
Found the problem.
Workaround solution, remove the vga-xxx argument from the kernel line in /boot/grub/menu.lst

Source RPM: (none) => kernel

Comment 10 Bit Twister 2013-11-17 07:33:29 CET
3.12.0-desktop-3.mga4 resolved the problem. 

$ journalctl | grep 'kernel: Command line:'

Nov 17 00:22:07 wb.home.test kernel: Command line: BOOT_IMAGE=mga4_64_beta1 root=LABEL=cauldron nokmsboot vga=790

Status: NEW => RESOLVED
Resolution: (none) => FIXED
