I also have an Acer Aspire 5100 and am experiencing flashes on the screen after resuming from suspend. I'd love to help but have no idea where to start (even in reporting the bug properly).

[OTHman (amir963ma)]

having the same problem,
plus I can't put my laptop to sleep or hibernate because it doesn't resume.

[gio10 (giovanni-martinelli10)]

I have similar problems on the same laptop.
1. resuming from suspend the image on the screen flashes
2. on 9.04 I solved by adding those lines in /etc/pm/config.d/00sleep_module
ADD_PARAMETERS="--quirk-vbe-post --quirk-vbemode-restore --quirk-vbestate-restore"
I upgraded to 9.10 and the problem 1. is still present.
If I do the modification of point 2 the system hangs during resume.

I can attach any log if needed, please, just tell me what you need. Thanks

The same bug on Aspire 5101 - screen flashes after resuming from suspend.
is there any solution for ubuntu 9.10?

Acer 5100-5674 experiences 'flashing' after resume from suspend on both 10.04 i386 and amd64 distributions.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

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.

Marco's solution does not work for a 32bit system on Ubuntu 10.04 LTS.

[Larry Cullen (fieldguy7-deactivatedaccount)]

Marco's solution does not work for 64-bit Ubuntu 11.10.

[Chris (cmavr8)]

I re-reported the bug as suggested by brad-figg.

BTW: Marco's solution did not work for me either in 64-bit Ubuntu 11.10.
