I sent a 'subscribe' to <mailto: debian-user-REQUEST@lists.debian.org> but didn't get an answer (or at least I didn't find it).The reply comes back to the address you subscribed from. Maybe that wasn't hans@hanswkraus.com. But we will not dwell on that; you can sort it out at another time.How do I switch drivers under Debian, especiallay from the "AMD FGLRX driver for Radeon adapters" to the "free radeon driver, which is the default in jessie"?I did not mean to imply you are using the FGLRX driver. Your "lspci -v" output shows > Kernel driver in use: radeon which implies otherwise. But the journalctl output doesn't look happy. To answer your question: dpkg -l | grep fglrx Lines with "ii" indicate installed packages. Purge and see what a reboot does.
root@robbe:~# dpkg -l | grep fglrxii fglrx-atieventsd 1:15.9-4~deb8u2 amd64 events daemon for the non-free ATI/AMD RadeonHD display driver ii fglrx-driver 1:15.9-4~deb8u2 amd64 non-free ATI/AMD RadeonHD display driver ii fglrx-modules-dkms 1:15.9-4~deb8u2 amd64 dkms module source for the non-free ATI/AMD RadeonHD display driver ii glx-alternative-fglrx 0.5.1 amd64 allows the selection of FGLRX as GLX provider ii libfglrx:amd64 1:15.9-4~deb8u2 amd64 non-free ATI/AMD RadeonHD display driver (runtime libraries) ii libfglrx-amdxvba1:amd64 1:15.9-4~deb8u2 amd64 AMD XvBA (X-Video Bitstream Acceleration) backend for VA API ii libgl1-fglrx-glx:amd64 1:15.9-4~deb8u2 amd64 proprietary libGL for the non-free ATI/AMD RadeonHD display driver
Is it OK to purge all these?
(What does the glxinfo command give?)
