Can confirm I have the same (or similar) issue, but this is limited to my 2nd VGA head only. The 1st is fine, no flickering.
Installation is a recent upgrade from 10.10 x86_64 (fully updated, no third-party repos) to 11.04. GPU hardware is a Radeon HD3450, *no fglrx*, the rest of the chipset/CPU are all Intel-based. The flicker isn't related to activity and occurs every 20-30 seconds, with both the 2.6.38-7-generic kernel from the natty repository and 2.6.39-rc1 from the kernel PPA. Similarly both Unity and 'Ubuntu classic' interfaces are affected. I have also upgraded mesa/xorg/drivers with the xorg-edgers repository, to no avail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/749347 Title: flicker on screen -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
