One small point concerning the automatic graphics configuration:
the earlier 6.2-5 iso selected "nv" for my graphics driver which is
correct, whereas the 6.3-pre2-r1904 iso chose the "vesa" option
With the attached patch to xorg-udev-rules generator, the CD will select the
"nv" driver for all chips which the driver tries to support, including
unknown ones. However, I am in doubt: there may be an unknown chipset for
which the "nv" driver opportunistically tries to work but fails (and "vesa"
would be the correct choice then). Should I commit this, or leave the
situation as it is plus a quirk specifically for 10de:0295?
BTW, this is the first time I see that "vesa" doesn't work.
