Yes! It works. Thank you very much. I installed Ubuntu using alternate CD an flickering/shaking was still there. Then I changed grub2 as you suggested and now everything works perfectly.
I did it this way: 1. add "radeon.new_pll=0" after "quiet splash" to the file /etc/default/grub : GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.new_pll=0" 2. run command: sudo update-grub 3. check if in your /boot/grub/grub.cfg is something like this: linux /boot/vmlinuz-2.6.32-17-generic root=UUID=accec70e-54ff-436b-a1f9-6f0a69411799 ro quiet splash radeon.new_pll=0 initrd /boot/initrd.img-2.6.32-17-generic 4. restart ------------ Before this, I tried it with the same good result right in grub2 menu (temporary way): 1. Press SHIFT during boot 2. Press "e" to edit grub2 options 3. Add radeon.new_pll=0 at the end of line "linux /boot/vml..... 4. Press Ctrl+x -- [RV515] Screen is shaking few minutes after boot https://bugs.launchpad.net/bugs/543265 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
