[opensuse] IBM X40 Screen is extremely dark when resuming from suspend
Running openSUSE 11.1 KDE 4.2 with Intel integrated card. Suspend to hard disk performs just fine. Suspend to RAM also works great, except for one big problem. When resuming from suspend, the screen is extremely dark, so dark you can barely see what you're doing. Adjusting the brightness controls or restarting X doesn't do anything. It is not until I reboot the computer does it operate properly. It looks like a back light is turned off or something when it goes to suspend but doesn't get turned back on when resuming. Maybe a kernel module that is unloaded and not loaded back? Didn't find a bug report on this so has anyone else experienced this and does anyone know what I can do to fix it? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Found a bug reported in launchpad that described my very same problem: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/292256 It was suggested to try s2ram --force --vbe to reset the graphics card's vbe state after a suspend. I tried it from the command line and it solved my problem. Now the question is how do I get the the Suspend to RAM option use s2ram with the --vbe option? I found this forum posting: http://forums.opensuse.org/hardware/392914-need-help-fixing-suspend-ram.html and explained that s2ram options can be set in a file called config. Therefore, I put S2RAM_OPTS="--vbe" in a file called config and saved it in the /etc/pm/config.d directory. Rebooted my computer and, after logging in, I shut the lid to my laptop, watched it suspend, opened it back up, and my system was up in a blink of an eye. Amazing! I hope this helped someone out there and I thought I'd pass it along. If there is somewhere else that this would be well suited, please direct me there. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You should file a bug at https://bugzilla.novell.com/ with reference to the ubuntu bug. Regards Dave P -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
