Bug Description
Binary package hint: xorg
This bug is related to bug 318325. I did a clean install of Lucid on this Acer Aspire 5100 (ATI Radeon Xpress 1100). On initial login the display is fine. After resume from RAM the screen flickers to the point the machine is unusable.

The "workaround" that Id2ndR posted does work in Lucid. What I did, until this bug is fixed, is created a bash script that runs on startup that executes that command. It's a horrible waste of CPU cycles... but hey, the screen isn't flickering.
The bash script, called stop-flicker.sh, looks like:
#!/bin/bash
while true ; do echo "toto" > /dev/null ; done
I then gave the script execute privileges:
sudo chmod +x stop-flicker.sh
You could execute this every time your screen flickers... but instead I added a custom startup application, System -> Preferences -> Startup Applications -> Add
I gave it the name Stop Flicker and gave it the command /home/$ user/stop- flicker. sh
Where $user is your user name...
This is hacky... but it works. Please fix this bug soon!
