At any rate, what are my options now?
Could it be possible to downgrade to the working state? Google tells me about 'yum downgrade', but is it a good route in this case? Should I and could I go back to 6.4? Or could I try to identify a particular package?
Or is it more promising to try to reinstall?
Also, is there a hope that I could find a workaround with some configuration file, like xorg.conf?
I followed the following, found at
https://ask.fedoraproject.org/en/question/10613/intel-82845g-integrated-grap...
from someone with the same problem:
* When your machine boots into the login screen (or a black screen with cursor if you are unlucky like me) hit CTRL+ALT+F2 to get to screen TTY2
* Login as root
* type 'init 3' to shut down the graphical interface
* type 'X -configure' (case sensitive)
* The new xorg.conf.new will be in root's home folder. optionally type 'cd /root' to get to that file.
* type 'nano xorg.conf.new' to open the file
* Find the line under "Device" which says 'Driver "intel"' and change it to 'Driver "vesa"'
* save and exit with CTRL+X, press 'Y' then hit <enter>
* rename existing xorg.conf, if any: mv -i /etc/X11/xorg.conf /etc/xorg.conf.old
* copy your new file with "vesa" line to the right place: cp /root/xorg.conf.new /etc/X11/xorg.conf
* start in graphical mode with 'init 5' or just 'reboot' and let things start up again.
In my case, there was no "intel"; instead, the line was 'Driver "modesetting"'. I first replaced 'modesetting' by 'vesa', but it failed. Then I kept the file without modifications, i.e., with 'Driver "modesetting"' and it worked.
