Red Hat Bugzilla – Bug 425351
Xorg sometimes starts a blank screen with i810
Last modified: 2012-04-17 17:08:20 EDT
Description of problem: On a Dell SX280 with an Intel video card and the i810 driver, X will sometimes start, but other times just creates a blank screen. As far as I can tell, Xorg is running and the log file makes it seem like it's running as well. This happens on multiple machines. Version-Release number of selected component (if applicable): xorg-x11-drv-i810-1.6.5-9.6.el5 How reproducible: Sporadic Steps to Reproduce: 1. Boot up the machine, sometimes works, sometimes doesn't. 2. init 3;sleep 5;init 5 3. Again, sometimes works, sometimes doesn't Actual results: Sometimes Xorg starts and the display comes up. Sometimes, it just produces a blank screen. Expected results: Additional info: [root@nulato ~]# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04) The display is a Dell 2001FP, using DVI on both ends. Following a suggestion found on another bug report, I started Xorg without an xorg.conf files. I have attached the Xorg.0.log file from that attempt.

FWIW: I can't use the i810 driver anymore since RHEL 5.1 on an IBM SurePOS 565 (specific Point-of-Sale hardware, also with 82915G/GV/910GL), while RHEL 5.0 worked fine! Starting the X server *always* (at least every time I tried) results in a blank screen, keyboard/mouse can not be used (e.g. to switch to a text console), but the X server stays running and the Xorg.0.log file doesn't show any errors. The vesa driver works ok.

I have experienced similar behavior with Fedora 9 on my Dell 700m laptop running the 82852/855GM Integrated Graphics Device as the VGA controller. Sporadically, the screen will blank and hard drive starts racing when I log out or just prior to gdm loading during startup. The X server always starts fine during bootup, but the black screen appears when the graphical boot screen switches to the login screen. I have encountered this issue up to half the time I login/logout since Fedora 8 (although it seems less frequent in Fedora 9). I wonder if it is perhaps related to changing screen resolution? I saw a recent bug fix for Ubuntu 8.04: https://launchpad.net/ubuntu/+source/xserver-xorg-video-intel
No further hardware enablement updates are planned for RHEL5's X stack. If this issue is still present in RHEL6, please update the affected product version and reopen this bug.
