X problems in Stretch with AMD APU?
And what kind of kernel is installed 4.9 or 4.11? Check the kernel log to see if the firmware has been loaded. >> I have a home theatre PC with an AMD A6-3500 APU. Bit of an oldie but still plays everything fine. The drivers supplied by the Jessie repositories (including fglrx for hardware acceleration) worked fine. But then I upgraded to Stretch and suddenly started without X. The debian supplied drivers don't seem to support the A6 any more? I got everything working again 3 weeks ago by installing the proprietary drivers (catalyst 15.9). But now X has gone again and the same catalyst package refuses to install. The error message that the installer gives is that the X version is too low for catalyst? Then I removed (--purge) xserver-xorg-core and reinstalled it. But when I now start X it says 'no screens found'.. Is there a way to get the AMD APUs off that generation working in Stretch working again? Or to at least start X again (with a very low resolution, assuming basic hardware)? << Add non-free to sources.list update install firmware-amd-graphics etc. <<.
