Description of problem:
(I apologize if this bug doesn't belong here.)
When I configure the kernel to include AGPGART with the intel-agp module on a Dell Inspiron 8100 with i815 chipset, the screen will not come back from suspend. If I disable AGP (either by recompiling the kernel without AGPGART, or with AGPGART and intel-agp as modules and then turn them off in xorg.conf), resume works fine.
Other info: I have nVidia GeForce 2Go video card and the latest Nvidia driver. From what I have read, AGPGART does not support resume on certain chipsets. I will be glad to provide other info if someone could point me in the right direction. (I am a newbe.) Thanks.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure kernel to include AGPGART (under drivers/char) and select support for intel chipsets. (These options are enabled by default if kernel is installed from rpm.)
2. Boot, start x (KDE). Use klaptop to place system in suspend.
3. After system is in suspend, press power button.
Actual Results: Screen remains black. Unable to switch to console. Must reboot machine.
Expected Results: System comes back from suspend with active screen. This happens if kernel is configured NOT to include AGPGART.
