Happens for me on Utopic with an Acer Extensa 5230E (Intel 4500M) using Kubuntu Plasma 5.1.1. Usually everything works fine until I start a new lightdm/sddm (tried both, doesn't matter) session on VT8 and switching back to the old session (VT7). VT8 is also corrupted if I switch there.
I did not experience this bug until I switch from 14.04 x86 (KDE 4.14.1) to Kubuntu 14.10 x64 by complete reinstall. Also I upgraded RAM to 3GB and tested it well with MemoryTest (no errors), but could it be some sort of corruption in graphics memory, because this laptop allocates graphics memory when needed (At least it seems to do this). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/659434 Title: Font/image corruption after resume from hibernate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/659434/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
