Suspend only works when the fglrx.so kernel module is not loaded.

[PashaP]

I have a Lenovo Thinkpad T60. On my laptop running Fedora 7 32-bit
2.6.22.4-65.fc7 with ati-driver 8.40.4. However suspend only works when the
fglrx.so kernel module is not loaded. If I use fglrx driver and laptop go to
suspend I see on screen:
---
Stopping tasks...
Suspending console
---
then hung

If I use standard driver (vesa) my laptom go to suspend without any problem.


Please help me solve this problem.

Thanks

I have exactly the same problem with FC7, kernel 2.6.22.4-65 and livna fglrx 8.40 on a Sony vaio laptop
No suspend problem with radeon or other generic video driver ...

Same problem here with any of the 2.6.22.x kernels and the ATI 8.40.4 drivers. Had to downgrade to 2.6.21-1.3228.fc7 kernel to get suspend and hibernate to work again.

How correctly to make downgrade to 2.6.21-1.3228.fc7 kernel?
Thanks

See this post here

I was downgraded to 2.6.21-1.3228.fc7 kernel and I have a problem with my Wi-Fi card and more any problem I think it is possible to solve these problems, but can be eat other way to solve a problem with suspend?

I've not been able to find another way to solve the problem with suspend.

From what I can find it is not possible to have the latest kernel, and the latest ATI drivers, and have suspend and resume working too.

It is very a pity: (
May be I can will use other driver for may video card (ATI Technologies Inc Radeon Mobility X1400) so I would like using the compiz?

I'm was registering a bug on ATI bugzilla but not responding from ati :-(

Try disabling the framebuffer in your grub config:

Add vga=0 to the kernel line in /boot/grub/menu.lst, for example:

kernel /vmlinuz26 root=/dev/sda3 resume=/dev/sda2 ro vga=0

You'll need to reboot before attempting to suspend again.

[BlueC]

doesn't that only fix potential problems with "waking" from suspend/hibernate?

[thayerw]

Well, the way I see it is there's nothing to lose by trying it and everything to gain if it works. In my experience with the fglrx driver it has addressed the symptoms described by the OP.

PS: As far as I know, it is the only way to successfully suspend a machine using the fgrlx driver.

I was added this parameter
kernel /vmlinuz-2.6.22.4-65.fc7 ro vga=0 root=/dev/VolGroup00/LogVol00 rhgb quiet

then reboot but I don't have a suspend ((

[BlueC]

no dice here either with vga=0 - still suspend hangs at "suspending console"

[j_laszlo]

Not working for me either.
