Fedora 10 resuming from suspend - blank screen

[crisponions]

I have a dell e1705 and am having problems resuming from suspend to ram on Fedora 10. When I resume, the screen is blank and the keyboard is unresponsive, I have to hit the power button to hard reboot. I figure this must be a X thing as the wireless module loads back up (the wifi light starts blinking) and there is disk activity.

Video card - Mobility Radeon x1400 (I know the current ati driver doesnt work with the newest xorg)
Wireless - 3945G intel

Any ideas would be helpful.

I have the exact same problem on a ThinkPad T60 with Radeon Mobility X1400.

In Fedora 8, I had the following in rc.local (but it is no help in F 10):

# Turn on correct suspend flags for T60
echo 3 > /proc/sys/kernel/acpi_video_flags

I have the same problem on an Samsung X460 with Nvidia 9200M

i have a similar problem on two laptops. on my hp pavilion zt3000 i suspended and when it woke up i got all sorts of colors on the screen and had to manually reboot. when i logged back in there were no icons on my desktop and i couldn't access any folders. i tried logging in as root but was told that no such account existed. i rebooted in init 3 and all my data was still there so i had to backup in text mode and re-install. now i'm scared to put this machine to sleep for fear of having to re-install

on my other machine, a pavilion dv7t on resume i get text errors regarding ata controllers etc. after a reboot everything is fine.

Has anyone checked to see if your screen is locked?

Gnome Main Menu--> System--> Preferences--> Look and Feel--> Screen Saver

When the screen saver activates--- for some reason it's tied in somehow to the power management stuff so that if you suspend the screensaver may not be running but... if you have it enabled with a tick mark in that box and you have ticked the option box for locking the screen.... to reactivate (resume from suspend) you need to provide the user password.

I can't confirm this will work in Fedora, but I added splash=0 (zero) as a boot option in Grub and that fixed
the problem with resume for me with Mandriva 2009.

Even I can confirm this problem. I have Vostro 1400 Laptop with Nvidia graphics. I have tried suspend with and without the Nvidia driver and in both cases suspend to HDD and RAM doesnt work.

All I get is a black screen and unresponsive keyboard, so I have to hard reboot. It works in Ubuntu 8.10 though.

I have the same problem on a ThinkPad T61 with an Intel graphics chipset. It does NOT happen if I suspend from a text console, fluxbox, or KDE with Desktop Effects turned OFF.

[Deore]

Same problem here, ATI Radeon 2400 HD. Might be a kernel issue: previously I had fedora 8 on this machine and with the last kernel available for f8 suspend didn't work too. Before that last kernel (forgot which one) I had no problems with suspend.

I have this issue (ATI V5200/thinkpad T60p) but *only* if desktop effects (compiz) are enabled.

With them disabled suspend/resume works fine with either the ati or radeonhd drivers.

[Deore]

I can't enable desktop effects in the first place (with both radeon or radeonhd drivers in spite of having direct rendering). Upon resume the whole systems seems to freeze - even the caps lock light doesn't light if I press caps lock. The guide for common kernel problems suggest how to get some information what can cause this, but for me "hash matches" in the dmesg output gives no clue (see the guide).

I tried the kernel mentioned above, it did not work for me. I tried suspending to ram from kde with desktop effects turned off. I will try suspending from a VT later and report back.
