Sorry for the delay in responding! The next thing to check here would be the 2.6.37-rc1 kernel available here: http://kernel.ubuntu.com/~kernel- ppa/mainline/v2.6.37-rc1-maverick/ . That includes a(nother!) re- working of the monitor frequency code. The radeon.new_pll option has been removed from the new kernel - as upstream is confident that the new code should work better - so you will need to remove it from your grub configuration.
If the new kernel still shows this problem, then the dmesg log would again be useful. The logs you attached previously didn't have drm.debug=0x04 set - you can see this on the “kernel command line” message: ... [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-25-generic root=UUID=4b588e34-b43c-4f8a-bd71-3abedbf91031 ro quiet splash radeon.new_pll=0 ... That should have “drm.debug=0x04” in it, and for testing the 2.6.37-rc1 kernel should not have “radeon.new_pll=0” in it. -- system cannot display extended desktop on Samsung 2333sw https://bugs.launchpad.net/bugs/664646 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
