Red Hat Bugzilla – Bug 465190
Lenovo X200 backlight disabled after resume from hibernate
Last modified: 2018-04-11 12:41:13 EDT
Description of problem: If I suspend my Rawhide Lenovo X200 to RAM, the backlight stays black after I resume it. I can't use the intel driver (notionally the right driver for this hardware) because it's broken. The nature of the breakage has changed several times over the past few weeks, so the vesa driver is the current safe harbour. My workaround is to modprobe the i915 driver in /etc/rc.local. Version-Release number of selected component (if applicable): xorg-x11-drv-vesa-2.0.0-1.fc10.x86_64
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) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. What problems you have with intel driver? Are there bugs filed for them? We will review this issue again once you've had a chance to attach this information. Thanks in advance.

The intel driver has been broken in a variety of ways. It was freezing the display (last week), then it didn't load at all due to an ABI mismatch against the X server (yesterday), and now it apparently doesn't survive a suspend-resume cycle. I'm actually using it at the moment, but I'm afraid to suspend my machine. I've also had to disable the e1000e kernel module so that Xorg won't brick my machine. Interesting times :-)
Loading the i915 module is enough to make the backlight resume properly, even when using the vesa driver for X.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
