Finally the problem was coming from passing nomodeset to the kernel command line.

None of the ccsm workarounds seem to help though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1439786 Title: 10de:0cbc [HP EliteBook 8540w] Max resolution of 1024x768 with nouveau To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1439786/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
