For anyone interested, I have found a solution for my Acer Aspire 5100 in
UBUNTU 11.04 (64bit version)
The flashing screen is caused by the kernel modesetting feature (KMS) that
doesn't work good on the ATI radeon xpress 1100 graphic chip, so I disabled
this feature by editing the file "/etc/default/grub" and changing the line:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to: GRUB_CMDLINE_LINUX_DEFAULT=”quiet
splash nomodeset”. Then I ran: sudo update-grub. Don't know if this is working
for ubuntu versions below 11.04.
For the googlers around here's the sequence:
1) open the terminal and type: gksudo gedit/etc/default/grub
2) find a line that says: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
3) modify that line this way: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash
nomodeset”
4) save, go back to terminal and type: sudo update-grub
5) reboot your laptop, then try to suspend it and resume, it should work.
Hope this helps someone.
