Bug#568207: Test results with 2.6.34-rc6
I tested 2.6.34-rc6 yesterday (with xserver-xorg-video-intel 2:2.11.0-1 and xserver-xorg-core 2:1.7.6.901-3), and the new kernel showed some improvement. Even with an external monitor attached to my ThinkPad X30 laptop, the X server starts correctly and provides a stable graphics display on the internel LCD screen. In other words, with 2.6.34-rc6, I no longer need to unplug the external monitor before starting X to avoid the blank screen problem. Unfortunately, some problems remain: * Extensive rendering artifacts at 24bpp (16bpp is fine). * Flashing and jumping (horizontally) images on the external monitor. It looks like the kernel driver failed to properly configure the VGA output DAC. Switching the external monitor off-and-on with xrandr has no effect on the problem (i.e., it does not help). For now I am staying with 2.6.34-rc5. -- Chuan-kai Lin http://web.cecs.pdx.edu/~cklin/ -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

I think the problem I am experiencing is the same as (or is very closely related to) Linux kernel bug #15070.

This is a quick report: I just upgraded to xserver-xorg-video-intel 2:2.11.0-1 and Linux kernel 2.6.34-rc5 on my ThinkPad X30 laptop (830MG graphics adapter). X works fine if there is no external monitor attached to the laptop when I start the X server. If there is an external monitor attached to the laptop when I start the X server, X produces a blank black screen on both the laptop and the external monitors, and there are no kernel error messages: kernel: i915 :00:02.0: setting latency timer to 64 kernel: [drm] set up 15M of stolen space kernel: [drm] initialized overlay support kernel: fb: conflicting fb hw usage inteldrmfb vs VESA VGA - removing generic driver kernel: fb1: inteldrmfb frame buffer device kernel: registered panic notifier kernel: [drm] Initialized i915 1.6.0 20080730 for :00:02.0 on minor 0 The system still responds to SysRq keys after the X malfunction. Note that xserver-xorg-video-intel 2.11.0 *requires* kernel modesetting, so users who are still on 830MG may want to stick to 2:2.9.1-3 (which does not require KMS) until the problem is resolved. -- Chuan-kai Lin http://web.cecs.pdx.edu/~cklin/ -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
