My experiences are the following: Everything works like before, including ethernet, wifi (still buggy on the EeePC), bluetooth (still buggy on the EeePC), sound (still buggy on the Compaq), SD card reader, USB, webcam (Finally fixed on the EeePC!).

But X is different. The symptoms described in this report are gone, but there are different ones: -GLX drawing glitches. -Once backlight switched off for powersaving reasons, it won't be turned on again until a suspend/resume cycle.

The latter has possibly been fixed by the latest commit in xf86-video-intel:

From 33c08882c0d551afb28baef643279901dcc65fa9 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 17 Nov 2010 16:37:53 +0800 Subject: [PATCH] Mark outputs as DPMSModeOn and restore backlight at mode set

The kernel always turns monitors on when doing mode setting, and so no further DPMS action is required. Note this in the mode setting code by marking the updated DPMS mode and restoring any saved backlight level.

Unfortunately this requires drm patches not pulled into *any* reasonable upstream branch yet. I have access to them. They'll end up upstream eventually, but will eventually be split up in more patches before. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Moreover, my impression is that XGL performance with the HEAD kernel seems to be slightly smoother than it was with the 2.634 kernel when actually not slowed down. So, this might be a kernel issue. What about asking kernel developers? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The backlight issue can be fixed/workarounded by going back to the openSUSE 11.3 (update) kernel.

No longer necessary. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

A lot of changes meanwhile in DRM, xf86-video-intel, libdrm, Mesa. So things might have improved. Could you verify whether your issues are still remaining when updating X11:XOrg and Kernel:HEAD once more?

zypper dup -r Kernel:HEAD zypper dup -r X11:XOrg

1: Ich wünsche dir ein frohes neues Jahr. 2. I started testing the mentioned repositories again. It was a bit problematic to install the new packages because x86_64 support seems to become incomplete in some repos. However, the new kernel and and X server seem to be better then ever before. I need a few days to make sure it's fully reasonable for users. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Once backlight switched off for powersaving reasons, it won't be turned on again until a suspend/resume cycle.

Yeah. I'm suffering from this as well. Could we track this in a seperate bug? Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
