Hello Xorg-Team, yesterday, I managed to update the VGA BIOS of the graphic card (using FreeDOS which was, in contrast to Microsoft DOS 6.2, able to execute the ubiosdos file from the Matrox utilities) recommended by Felix and as well updated the main board BIOS.
This did not solve the problem. The X server still fails to start (black screen) and returns to the text terminal. The logs notice a segmentation fault. Attached: a) logfile Xorg-deb10-190731a_0.log which - logs a start attempt introduced by systemd - uses a personal xorg.config file - uses the mga module compiled on my own b) logfile Xorg-deb10-190731b_0.log which - logs a start attempt introduced by systemd - without xorg.config file, using xorg defaults and hardware recognition procedures - uses the mga module from Debian 10 c) a diff-file between the log file with the differences between - the start procedure with Debian 10 (after upgrading from Debian 9 that failed with MGA driver version 1.6.5) which fails with MGA driver version 2.0.0 and - the start procedure logged in logfile b Best regards Markus
