Resuming from suspend results in black screen

[John Gruenenfelder]

This problem occurs with the most current snapshot of Hoary (kernel 2.6.24-14). The machine is a Shuttle SN95G5 nforce3 chipset with an Athlon64 X2 processor. The video card is an Nvidia GeForce 7600 GT. This is a desktop machine with a wired LAN connection.

I can suspend to RAM and it appear to finish properly. However, when I then try to resume, I get the same result. The screen stays black and X never displays. The machine is not entirely dead, though, because the HDD light blinks every 5-10 seconds. Also, if I press CTRL+ALT+DELETE, I get a flurry of disk activity and then it goes back to the 5-10 second blinking. Fortunately, I can use the Magic SysRq key combos to sync, unmount, and reboot the machine. The network is not active during this and I cannot SSH into the machine or even ping it.

These results occur using the binary Nvidia driver. I did try using the nv driver as well, but it was a couple weeks ago and so it isn't quite a fair comparison. In that case, resuming from a suspend did actually hang the machine requiring a manual reset. I was able to successfully resume the machine with the nv driver, however.

I really hope I can get this issue resolved as it is one of the only features not working with the latest Ubuntu on my system. I have not specified a package for this bug as I'm not sure if it should go against the kernel, the Nvidia driver, pm-utils, or something else.

Are you seeing this bug while using Compiz (desktop effects enabled)? Could you please verify, whether the issue is reproducible with desktop effects disabled (System -> Preferences -> Appearance -> Desktop Effects).

[John Gruenenfelder (johng-as)]

Yes, I am currently using Compiz with all sorts of details/effects turned on.

I did as you suggest and turned off Compiz (switching back to Metacity) and then tried both suspend and hibernate again. The results were identical. Seemingly correct suspend/hibernate phase, and then an almost-complete resume ending in the black screen. Again I was able to reboot the machine via the magic sysrq keys, but nothing else.

I'm experiencing the same bug, and I'd like to complete the missing info: why is it marked as incomplete? It sounds pretty hard to provide the Xorg.0.conf (assuming Xorg even starts) in this case, unless maybe by using a livecd?

I have an Hp Pavilion dv6200 and when I resume from suspend I get a black screen. Ubuntu 8.04 Gnome desktop. I did not install any proprietary drivers for my graphic card nor am I using compiz or beryl. This problem also occurs in Fedora 10.

I'm also experiencing the same bug, on a Dell Studio 1535 Laptop.

$ uname -a
Linux user-delllaptop 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux

The system is completely alive after resuming, the only problem is the black screen. The screen backlight is not on.
Key presses seem to work as normal - hence I was able to blindly capture the attached dmesg output.

Note: I unloaded the fglrx module prior to suspend - the bug is reproducible 100% of the time, with or without fglrx running, and with or without gdm running (this dmesg was captured after booting into single user mode).

[Bobnova (pskovinsky)]

I am also experiencing this.
I have a homebuilt desktop, it's a G31 motherboard with a e5200 (core2duo) chip, 4gb of ram and a ati 4830 video card, running 9.04 AMD64.

It hibernates happily enough, and on resume it goes through all the text (i have the splash turned off) happily, says it's loading the image file, then fires up gnome to a 1280x1024 (my monitor's max, and where i have it set) screen with a mouse cursor. The cursor moves normally, but there isn't anything to click on, nor does clicking do anything.

I have all the current updates for 9.04, and haven't changed anything power management wise.

I would be happy to test different things if someone can point me in the proper direction.

[Alex Nixon (alex-nixon)]

I've had limited success using tuxonice (https://launchpad.net/~tuxonice/+archive/ppa).

I'm still unable to suspend/resume using the fglrx driver, however using the 'radeon' driver, the tuxonice suspend script is able to successfully suspend and resume X, but after a resume VTs are still broken.

I experience black screen with radeon graphic carte without using proprietary driver.

John Gruenenfelder, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

[John Gruenenfelder (johng-as)]

I think this bug can be closed. I no longer have this hardware so I am unable
to test a newer kernel on it and that particular kernel version is very old.
