11.4 + DELL latitude + fglrx + nomodeset = black screen after resume

Hi,

My Dell Latitude with ATI radeon 4350 card fails to resume from standby - screen remains black. :confused:

I have to use nomodeset kernel option to prevent black screen on boot.

Radeon drivers is non an option duo to his power usage (unless someone know how to tell radeon to down scale when needed).

fglrx otherwise works more or less well, excerpt flash videos sometimes starts to be sluggish.

I’ve tried to google for solutions, but had no luck.

Any ideas/ other debug info needed?

…well, try not to go to standby :smiley:

Until you can sort this power useage problem, you could try the boot code:


pcie_aspm=force

I blogged about that here: GNU/Linux and openSUSE power management regressions - Blogs - openSUSE Forums
