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)?
