Running 14.04.2 on a X1 Carbon 3rd gen, suffering from the same problems. Especially when an external screen is attached, Thunderbird has corrupted fonts when opening directly on the external screen. If I open Thunderbird on the internal screen and move it over to the external, all is fine. Firefox also suffers from that (same rendering engine?), especially Google maps. Chromium doesn't show that behaviour.
As suggested in #67, #68 upgraded now to 3.19.0-12-generic. That makes the system at least bootable without having to break into the recovery mode (#64). And all the special keys now work :). But, the graphics problems are still there. I will try to add two screenshots. Maybe 15.04 has some more changes than just the kernel? I haven't tried that release yet, would love to stick with 14.04. ** Attachment added: "Thunderbird opened on external screen" https://bugs.launchpad.net/linux/+bug/1432194/+attachment/4389609/+files/Bildschirmfoto%20vom%202015-05-02%2018%3A00%3A22.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1432194 Title: Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1432194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
