Description Christoph Tavan 2004-08-13 07:34:52 UTC
Distribution: gentoo-dev-sources-2.6.7-r11 Hardware Environment: Samsung X30 WVC1500 laptop Software Environment: Gentoo linux. Kernel 2.6.7 with latest acpi-20040715-2.6.7-patch from acpi.sf.net applied. Problem Description: Laptop suspends and wakes up properly (after wakeup I can connect via ssh!) but the display remains black (no matter, whether I was in X, framebuffer or text-mode). Tips from /usr/src/linux/Documentation/power/video.txt didn's help. Steps to reproduce: echo -n mem > /sys/power/state Then press the Powerbutton.

I have the exact same symptoms with my Dell Inspiron 8600 w/WUXGA display and GeForce FX Go 5200 adapter. Using Fedora Core 2, tried a handful of kernels, including 220.127.116.11 w/acpi-20040715 patch, and plain 2.6.9-rc1. Also tried 'xset dpms force off' before entering S3, with no success.

Same here with X10. However, this program  activates the display, but it's still not usable.  http://www.doesi.gmxhome.de/linux/tm800s3/resources/boot-radeon.c
Comment 8 thomas 2004-08-29 23:18:57 UTC
I finally resolved my case. By uising a newer NVIDIA X-driver which supports ACPI, S3 suspending works perfectly (only from X, though). Maybe there's a driver for the Radeon card supporting ACPI as well?
Comment 9 Len Brown 2004-11-04 00:57:46 UTC
Christoph, is the Samsung fixed as the Dell was with an updated NVIDIA driver? Christian, how abou the X10? If it works in X, will virtual consoles still work after resume?
Comment 10 thomas 2004-11-04 01:05:24 UTC
Len -- yes, virtual consoles work fine after S3 resume here.
Comment 11 Christoph Tavan 2004-11-14 03:19:18 UTC
Hi Len, I tried it with the latest nvidia-drivers 1.0.6629 but I had no success: The display still remains black after S3 resume no matter whether I suspended it from X, fb-console or text-console. In the case where I suspend it from the console I can type "reboot" after resume and it reboots properly. Everything seems to work after resume except the display. I'm using 2.6.9 sources (gentoo-dev-sources-2.6.9-r1) at the moment. Any other Ideas? Thanks, Christoph

Can you check whether running the video_post utility from bug #3670 changes anything? Please try it from VGA console with no framebuffer.
Comment 13 Christoph Tavan 2004-11-14 14:09:23 UTC
Created attachment 4029 [details] Photo of Display after S3 resume with video_post As you suggested, Venki, I've tried your tool from the vga-console (and from the fb-console as well). Yeah, it did some kind of reactivate the display. But the display got white and then slowly turned to gray with some funny colored stipes (see attachment)... Christoph
Comment 14 thomas 2005-04-11 04:30:46 UTC
(Len,) It turns out my virtual consoles do not work after resume after all. Sorry for this late feedback. I'm now on 2.6.9/fc2 and nvidia driver 1.0.6629.
Comment 15 Jakob Schi 2005-06-17 01:05:56 UTC
I have the same problem with my Dell Inspiron 5150 laptop with A38 bios, the 2.6.11-gentoo-r11 kernel (essentially a 18.104.22.168 kernel) and binary-only NVIDIA driver version 1.0.7664. Suspend works if X is running (a part from the USB devices sometimes getting lost, and the fan running a bit fast afterwards), but all virtual consoles are messed up. If X was the active display the LCD display is filled with weird colors once I shift to a virtual console. If I was on a virtual console, it is black. A part from this the computer is working. /Jakob

I have the same problem with my Samsung M40 and Ubuntu 5.10. The display remains black after resume. From the console it can be reactivated by vbetool's post comand. Then it shows the strange behaviour described above.
Comment 17 Len Brown 2006-08-09 20:36:43 UTC
Video restore on S3 resume is the job of the BIOS or video driver, and is not part of ACPI. Moving to drivers/video.
Comment 18 Rafael J. Wysocki 2006-09-28 10:06:39 UTC
Problems with video after an S3 resume can be solved by the s2ram tool (see http://en.opensuse.org/S2ram). If that helps, please close this bug.
