Description Mildred 2009-04-09 22:19:10 UTC 
Description of problem:

It only occurs when booting from EFI. (I also have a problem when booting from legacy BIOS with KMS enabled but it seems different, I can go as far as seeing the mouse cursor then).

I boot Fedora with the following grub command line:

root (hd0,3)
kernel /boot/vmlinuz-2.6.29.1-54.fc11.i586 root=/dev/sda4 rhgb ro
initrd ...

In that case, I get a Plymouth running nicely. If I press ESC, I get into console mode where I can see the startup messages running. Works nicely until Xorg try to start. Then, the computer freeze completely, the screen is left with what was on it. Keyboard doesn't work the slightest bit. I can tell it's when Xoth is starting because the message I can see on the console are the messages displayed just before Xorg starts. In my case:

Starting Avahi daemon ... [OK]
Registering binary handler for Windows applications [OK]

(those are the last lines)
The only solution, hard-reboot. CTRL-ALT-DEL doesn't work.


Now, when I try to disable the kernel modesetting using the following command line in GRUB:

kernel /boot/vmlinuz-2.6.29.1-54.fc11.i586 root=/dev/sda4 nomodeset rhgb ro

I get a jammed screen during the startup. When Xorg tries to start, I get my screen blinking for something like 3à seconds perhaps. It seems that it's the backlight that's blinking. Sometimes the screen go black, sometimes I get the same jammed pattern but brighter, alternating with the usual dim jammed pattern.

After some times, xorg seems tried to start, and I get stillness (the screen is still jammed). Ctrl-Alt-Del restart the computer.


Then I tried to start using different video devices in the kernel command line (video=efifb, video=vga16fb, video=intelfb). Doesn't changes anything.

I tried to set an xorg.conf file with Device "intel", but it doesn't change anything (I guess xorg autodetected "intel", so it shouldn't have any effect).

If I put Device "vesa", and start with KMS, I get the framebuffer console working. When xorg tries to start, it blinks very quickly and for no more than two seconds, then stops. I can then enjoy the framebuffer text console. I can login successfully on /dev/tty2.



Version-Release number of selected component (if applicable): rawhide 9 april 2009
How reproducible: always
Actual results: can't start Xorg
Expected results: to be able to start Xorg
Smolt profile: http://www.smolts.org/client/show/pub_1b47fd66-9ccf-497f-8314-ad2c42673f02

I should be able to provide more information if requested.
Comment 1 Mildred 2009-04-09 22:21:51 UTC 
I got Fedora rawhide by installing Fedora 10 in legacy mode (BIOS emulation) and upgrading it. I currently use it with no problem provided that I disable KMS (nomodeset)
Comment 2 Matěj Cepl 2009-04-10 17:05:03 UTC 
Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf, if available) and X server log file (/var/log/Xorg.*.log) to the bug report from both EFI and non-EFI boot as individual uncompressed file attachments using the bugzilla file attachment link below.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Thanks.
I'm attaching here the simple xorg.conf that I used to force driver intel or vesa in X.org. Now that I think of it, I should test the driver fbdev as well (I read it somewhere on the Internet)

Xorg.0.log legacy mode, no KMS

Attached also the Xorg log that I get when booting Fedora as a legacy system (BIOS emulation), KMS disabled.

Xorg.0.log.old EFI, KMS enabled, no video driver specified on kernel cmdline

I Noticed that when I started Fedora in EFI mode, with kernel modesetting, I had a jammed screen for perhaps less than a second, before I could see Plymouth.

And while Plymouth was running, the last 5 lines of pixels (approximatively) seemed wrong. Sort of jammed in a way. It seems that they display some part of the Plymouth animation, but not so that they formed any meaningful image.

I hope that those log files are enough :)

Thanks
Mildred

Comment 8 Adam Williamson 2009-05-25 19:31:44 UTC 
This looks to be a dupe of 494390 - same adapter 8086:27a2 in a Mac system, same symptom (no X without 'nomodeset').
