Torsten. I also tried updating the kernel to 3.19 (on 14.04) first rather than installing 15.04. But once I updated and rebooted my wifi stopped working (the driver was not detected). Afterwards I did a fresh install of 15.04 and it has been over a week and I have no font issues..
I think you can first try using a live usb with 15.04 and use it for a while and see if you get any issues. -- 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
