Display Problem - Pincushion Distortion
After an upgrade my display has severe pincushion distrotion apparently
caused by lilo. That is, at power up the initial display is normal but
distorts as soon as lilo starts to present the boot options. The
uncommented line in lilo.config is vga=normal. I have tried switching
this to vga=ask which, according the man pages for lilo and lilo.real
(whatever this is), at startup lilo should pause and can display the vga
options. It doesn't pause.
The upgrade was fairly straightforward: I upgraded a system from potato
running xwindows and gnome to woody first from an official cd set using
apt-get -f install dpkg apt debconf
then
apt-get -f dist-upgrade
then when on line and repeated
apt-get -f dist-upgrade
and finally
apt-get -f install xserver-xfree86 xfonts-base
and
apt-get -f install gnome-utils gnome-contol-center
gnome-users-guide gnome-media
This, plus some fiddling with dpkg-reconfigure xserver-xfree86, produced
a reasonably workable system but the pincushion distortion persists.
(I don't understand why, when a I had a perfectly working xwindow/gnome
display in potato, it is necessary to reinstall xwindows and gnome. I
would have thought that a dist-upgrade would take care of this. I also
don't care for lilo's orange block in the middle of the screen at
startup. I have a far more detailed bootmess.txt. But all this is
besides the point. The pincushion distortion is the only real irritation.)
