I had related problems - the graphics on the Plymouth graphical loader screen were corrupted. Also my Thinkpad would not wake from sleep or hibernation. The instructions I posted elsewhere might be helpful for you... My issues weren't exactly the same, but similar. To resolve the sleep issue, I added "nomodeset" to the kernel parameters. This enabled the machine to suspend and resume correctly, including hibernation. Unlike 10.04, in 10.10 the X server starts normally in 1024×768/16M colours and the machine is perfectly usable. I amended the following line by adding "nomodeset" to the end in /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" I then ran update-grub to enable the change. However, the nomodeset line means that the plymouth graphical loading screen no longer works. It is replaced with a text-based one. In the hope of at least running in the native resolution of the LCD and getting a smoother text loading screen, I added a vga mode parameter to the same line, as follows: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset vga=792" This not only worked and reset the console resolution to 1024×768, but it also re-enabled the graphical loading screen, which furthermore now appeared with the correct colour palette, removing the coloured fringes that had affected the default install. I then dropped the X screen from 16M colours to 65K colours, which gives a sharp increase in display performance & enables me to use dual-head with an external monitor running at 1280×1024. I have documented how I did this in a blog post here: http://liam-on-linux.livejournal.com/20637.html I then amended the GRUB line so that the bootup screen mode was the same as the X one: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset vga=791" The result is that everything now works: graphical startup & shutdown, suspend & resume, hibernation, and a fast X display which supports dual-head operation. -- Liam Proven • Info & profile: http://www.google.com/profiles/lproven Email: [email protected] • GMail/GoogleTalk/Orkut: [email protected] Tel: +44 20-8685-0498 • Cell: +44 7939-087884 • Fax: + 44 870-9151419 AIM/Yahoo/Skype: liamproven • MSN: [email protected] • ICQ: 73187508 -- [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
