Red Hat Bugzilla – Bug 448024
White X with openchrome driver
Last modified: 2018-04-11 03:48:14 EDT
Description of problem:
When I boot the KDE live cd (Fedora 9) then the screen turns reddish then white
when rhgb loads or when loading X if I load w/o that parameter. After this
happened, I decided to try to use the vesa driver (xdriver=vesa) and that
doesn't work. It would load up to KDE but my screen would be blank the whole
time. I could tell it loaded up into KDE because I could hear audio. I tried
added Option ForcePanel to xorg.conf when I was using openchrome but to no
avail, all that did for me was turn red to purple then to white. Note that this
laptop works fine with Fedora 8 with openchrome with the Option "ForcePanel"
added. This is a regression. Feel free to move severity to medium but
obviously this is high and a show stopper for me :(.
Version-Release number of selected component (if applicable):
Default version in Fedora 9
Steps to Reproduce:
1. Load CD wait for rhgb to load
Screen turns reddish/brown then to white
To see rhgb.

Can you please add to the Device section of your xorg conf :
Option "ActiveDevice" "LCD"
and send the corresponding xorg log ?

X still doesn't start with those options. It goes blank. However, when I kill X
it says X: symbol lookup error: /usr/lib/xorg/modules/drivers/openchrome_drv.so:
undefined symbol: xf86strstr.
Not sure if that's useful or not.
The undefined symbol is indeed a bug. I got a fix for it, but the fedora build
system is currently under maintenance...
I am attaching a more recent xorg log. This is with your unofficial rpm that I
obtained on irc. Also if I let X go out to the end I can hear the KDE log in
music and it ends up with the screen being 1/2 black and the other 1/2 consisting
of multicolored vertical lines.

Latest xorg log
xorg-x11-drv-openchrome-0.2.902-5.fc9 might work better for you. Available from
Koji before it hits updates-testing.
Well it works better for sure. The first time I tried the driver it loaded X
(i.e. the screen came up with the options mentioned above) however it ultimately
froze before fully loading KDE and per usually I was unable to recover my X log.
The next time I tried it I had a scrambled X. So it looks like it's getting
can you please try adding Option "NoAccel" ?
or better, first try Option "AccelMethod" "EXA" and if it still doesn't work,
try Option "NoAccel".
Unfortunately that still didn't work. I am attaching a screen shot of what it
looks like with the parameters added that you've mentioned.

Could you please post the xorg log from xorg-x11-drv-openchrome-0.2.902-5.fc9
with Option "NoAccel" ?
Unfortunately I can't. It freezes my computer and I'm not able to ssh into it
to recover it.
Any more ideas? I am now running Rawhide in hopes it will fix my problem.
Seems the -7 openchrome driver gives a backtrace.
Chris, there's a new version in rawhide, xorg-x11-drv-openchrome-0.2.902-8.fc10.
Does it work ?
Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
I saw a white X a few days ago. It turned out to be the user account was set to
use compiz, but I logged in from a machine using qemu-kvm with cirrus emulated
hardware. The display was entirely white but I could tell that clicking things
was working. Manually removing the compiz option so it runs metacity instead
fixed the problem.
Not sure if this is the same issue, but I thought I would mention this.
I'm downloading the latest alpha version of f10 to test this and I'll report on it when it finishes. Also it's very difficult for me to track rawhide on this laptop when the last time I used it I had no X so I can only really test this at milestone releases like alpha, beta, etc.
This is bug can be closed. The openchrome driver on Fedora 10 alpha 1 is working.

Thx for testing, Chris. Could you please attach the xorg log and xorg conf ? I'll then close the bug.
No log, too bad, but the bug is fixed, so let's close it.
Thanks and regards,
Sorry. My laptop is currently broken and was just sent in to HP for repair. I'll report on this when I get it back.
