Bug#525619: xserver-xorg-video-intel: screen blank after returning to vt7
I see you're running 2.6.37, and it looks like there were some more backlight fixes lately, so you might want to try latest 2.6.38-rc from experimental. Thanks, I've just now looked at the shortlog entry related to the backlight. However, my backlight is fine: It turns off upon suspend and turns on upon resume. The problem is the display itself, which is blank upon resume (maybe 1 time out of 10). https://bugs.freedesktop.org/show_bug.cgi?id=34437 seems similar. -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of unsubscribe.

Bug#525619: xserver-xorg-video-intel: screen blank after returning to vt7
Hi, Sanjoy Mahajan san...@mit.edu (20/04/2010): I see a similar, perhaps identical problem. Twice now (today and a few days ago), the laptop has woken up with the screen almost completely black. I can barely see the windows, but the laptop is otherwise fine; for example, I can edit in Emacs if I could do it all without reading the characters. Cycling S3 sleep doesn't restore the brightness, nor does restarting xdm and the X server -- I need to reboot and then the screen is back to normal brightness. This is with xserver-xorg-video-intel 2.9.1-3 and kernel 2.6.33 (vanilla). I imagine that it has KMS -- I didn't do anything special to disable that when I compiled the kernel. could we please get an update, with either squeeze or higher?

Bug#525619: xserver-xorg-video-intel: screen blank after returning to vt7
could we please get an update, with either squeeze or higher? Alas, yes: I still see the problem. It happens every couple days where the screen is blank (but the backlight is on). A few days ago I had started filling out a new Debian bug report, but then got the hang again, rebooted, and lost track of the report -- which I just found and am appending the version info from it. When the problem happens, the backlight is on but the screen is blank, and I can do everything except see what is on the screen -- so I can switch to vt1, log in as root, and cleanly reboot. However, I found nothing interesting in any of the log files, whether Xorg.0.log, the syslog, xdm.log, or /var/log/messages. Since then I've added drm.debug=14 log_buf_len=16M to all grub boot-command lines (copied from a Fedora debugging X page). I've also prepared a script to run (typing blind and loggin in as root) when the problem next happens in order to get more debugging info: d=/root/debug-blank-display mkdir -p $d dmesg $d/dmesg.log cp -p /var/log/Xorg.0.log $d/ mount -t debugfs none /sys/kernel/debug dd if=/dev/mem of=$d/gpu_rom.dd bs=64k skip=12 count=1 intel_gpu_dump $d/gpu_dump.log Anything to add or subtract from that script? And here's what was in the half-finished bug report from Feb 20: Package: xserver-xorg-video-intel Version: 2:2.14.0-4 Severity: normal Every few days (so perhaps ten S3 suspend/resume cycles) the following happens. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.37 (SMP w/2 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages xserver-xorg-video-intel depends on: ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libdrm-intel1 2.4.23-3 Userspace interface to intel-speci ii libdrm2 2.4.23-3 Userspace interface to kernel DRM ii libpciaccess0 0.12.1-1 Generic PCI access library for X ii libudev0 166-1 libudev shared library ii libx11-6 2:1.4.1-4 X11 client-side library ii libx11-xcb1 2:1.4.1-4 Xlib/XCB interface library ii libxcb-aux0 0.3.6-1utility libraries for X C Binding ii libxcb-dri2-0 1.7-2 X C Binding, dri2 extension ii libxcb1 1.7-2 X C Binding ii libxext6 2:1.2.0-2 X11 miscellaneous extension librar ii libxfixes31:4.0.5-1 X11 miscellaneous 'fixes' extensio ii libxv12:1.0.6-1 X11 Video extension library ii libxvmc1 2:1.0.6-1 X11 Video extension library ii xserver-xorg-core [xorg-video 2:1.9.4-2 Xorg X server - core server -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of unsubscribe.

Hi, Sanjoy Mahajan san...@olin.edu (22/02/2011): Alas, yes: I still see the problem. I see you're running 2.6.37, and it looks like there were some more backlight fixes lately, so you might want to try latest 2.6.38-rc from experimental. You could also try building the intel driver from upstream git master (I can assist with that part). Since then I've added drm.debug=14 log_buf_len=16M to all grub boot-command lines (copied from a Fedora debugging X page). I've also prepared a script to run (typing blind and loggin in as root) when the problem next happens in order to get more debugging info: d=/root/debug-blank-display mkdir -p $d dmesg $d/dmesg.log cp -p /var/log/Xorg.0.log $d/ mount -t debugfs none /sys/kernel/debug dd if=/dev/mem of=$d/gpu_rom.dd bs=64k skip=12 count=1 intel_gpu_dump $d/gpu_dump.log Anything to add or subtract from that script? I'm afraid you'll have to ask upstream. Bug reports of interest: https://bugs.freedesktop.org/buglist.cgi?cmdtype=runnamednamedcmd=Driver/intel https://bugs.freedesktop.org/buglist.cgi?cmdtype=runnamednamedcmd=DRI/Intel If you see nothing matching your issue, I'd suggest reporting a bug there: https://bugs.freedesktop.org/ product xorg, component Driver/intel should be a good start.

In both cases, the backlight was still on, but the screen was blank. And switching back to vt1 or any other non-X vt, then back to vt7, did not solve it. However, putting the laptop into S3 sleep and then resuming solved the problem. can you still reproduce this with latest intel driver and kernel (with kernel mode setting)? I see a similar, perhaps identical problem. Twice now (today and a few days ago), the laptop has woken up with the screen almost completely black.
