The screen goes blank after we resume from S3, and it doen't matter whether we start X or not. It happens also in failsafe mode, where its just text.


Well probably it is not a Graphics Driver problem after all. Coz it doesn't matter whether you plug an external card or not ( or even use internal graphics, such as for the 855GM chipset) the same problem occurs.

Although i have not had the same problem on Windows, but here the culprit seems to be the Linux ACPI driver support. I have checked the problem on a DELL PC too, and its the same there too....

I looked for some workarounds, probably patches but none available as of now, doesn't look like  a BIOS problem either, coz the same Bios runs well on WinXp.

strange...

I'm guessing that when you set the system to standby... the power light on the display goes off, blinks, turns gold... it does something to indicate that it has also entered standby?

so... when the computer resumes... does the display also wake up but simply display nothing... or does it fail to power up?

Aloown3d.  :D

This is probably ACPI coding issues.  The 2.4 kernel had "alpha" ACPI and 2.6 is only so far along.

Try getting a new kernel update from Yast..or is -52 the latest?

In the upcoming days I soon will have to install Linux on a system with an ATI card.

How reassuring this is.

The ATI card won't give you any problems.
They just have very bad(slow) drivers.
