Created attachment 21607 [details] Xorg.0.log Bug description: I set a time for put display to sleep when inactive in gnome-power-manager. With compiz, after the LCD is off, there's no way to get it on again. Moving mouse or pressing the keyboard does not wake it up. Even more, when I press the "Caps Lock", the "Caps Lock LED" isn't turned on. I can still make acpid shut the computer down by pressing the power button. System environment: -- chipset: 965GM -- system architecture: X86-64 -- xf86-video-intel: x11-drivers/xf86-video-intel-2.5.1-r1 -- xserver: x11-base/xorg-server-1.5.3 -- mesa: media-libs/mesa-7.2 -- drm: x11-libs/libdrm-2.4.1 -- kernel: 2.6.28-gentoo -- Linux distribution: Gentoo -- Machine or mobo model: DELL Latitude D630 -- Display connector: LVDS Additional info: * I've tried gentoo's x11 overlay (xf86-video-intel-2.5.99.1.ebuild, mesa-9999.ebuild, ...), the same problem exists. * I'm not sure if this is related: I've done some tests with Linus' kernel git tree. Before (and including) commit 0a3e67a4ca, I got a "blank desktop" when I start compiz, nothing but a mouse pointer is on the desktop. With commit e0f0754ff6, compiz works fine, but the problem stated above exists.
hi jesse, how do you config your power management, you do suspend resume or only turn off display for a while? Thanks Ma Ling
Hi MaLing, I set a timeout for "Put display to sleep when inactive for", and set "Put computer to sleep when inactive for:" to never. No suspend/resume, just turning the display off.

Thanks Ma Ling
