At first: Thank you very much for the detailed hints! The system is all factory hardware, no parts have been replaced (it is still sealed). Stickers say: Hardware: Acer Aspire E500 EB7S, video card ATI Radeon X700 SE. No hints for AGP or not...
At first I've tried all possible values with your provided xorg.conf, include 1, 2, 4, 8 with a fresh reboot after each. Unfortunately the problems keep still the same. It also keeps the same when setting in BIOS all to default values (as far as I can remember, I never changed any BIOS settings). Next I've tried to remove ati-agp module from kernel with "modprobe -r ati-agp". Then a "lsmod" to check if the module is removed and again I've tried all possible values, include 1, 2, 4, 8, with a "service gdm restart" after each change (because after rebooting the ati-agp module is still there). And again, unfortunately the problems keep still the same. Next I've tried to disable "KMS" as described at https://wiki.ubuntu.com/X/KernelModeSetting , but again it doesn't work. I've tried to "modprobe -r" all relevant modules (radeon, agpgart, ati_agp, drm_kms_helper) and add them to "blacklist-<kernel-module- name>.conf" files in /etc/modprobe.d/ and next "update-initramfs `uname -r`-u". But still "KMS" is enabled after reboot and all ATI modules are loaded. I figured out that this behaviour seems to depend on automatic xorg configuration when no xorg.conf file is provided or when I use the part: <Section "Device" Identifier "Configured Video Device" Option "AGPMode" "<x>" EndSection> Only when I created a failsave xorg.conv with "VESA" defined, "KMS" is disabled and "blacklist-<kernel-module-name>.conf" files in /etc/modprobe.d/ were regarded. -- [RV410] Screen gets unreadable https://bugs.launchpad.net/bugs/559189 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
