multi-coloured vertical lines/nomodeset & suspend/resume

Asked by adam jvok on 2012-03-20

My laptop (a Panasonic CF-R4) was perfectly happy with 3.0.0.14-generic.

After the upgrade to 3.0.0.15-generic (and still with 3.0.0.16-generic), I never get to see the logon screen - instead the screen fills with multi coloured vertical lines.
Very pretty, but not a lot of use.
I can ssh to the box, so apart from the screen, it seems to be OK.

I can work around this by setting
GRUB_CMDLINE_LINUX="nomodeset"
in /etc/default/grub
and then
sudo update-grub

After that, I can boot and get the logon screen with no problems.

...BUT, with "nomodest" If I "suspend", then "resume" nolonger works - the screen just stays black, no sign of disk activity, not possible to ssh to the box.

Susepend/resume worked fine without nomdeset in 3.0.0.14-generic.

What I'd really like is:
1. Not to have to set "nomodeset".
2. To be able to suspend/resume normally.

Any ideas? Thanks.
