Hi Christopher, Sorry for the late response, i just read your email. The last correct functioning kernel is /boot/vmlinuz-3.13.0-95-generic
I did apport-collect for the kernel: Linux linux-desktop 4.2.0-42-generic #49~14.04.1-Ubuntu SMP Wed Jun 29 20:22:11 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux I found out that the problem occurs first at kernel image /boot/initrd.img-3.16.0-77-generic (Maybe also earlier) Should i do apport-collect for that kernel loaded too? regards -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1614442 Title: radeon 2.39.0 - 2.43.0, no scaling mode on RV515 PRO [Radeon X1300/X1550 Series] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1614442/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
