Intel GMA 4500M on 15.6" HD LCD
in acer travelmate 5735Z
screen is black after boot screen.
kernel 3.x problem.
see
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/744187
and others.
i keep approx. 10 gnu/linux systems running.
with kernel 3.x, i experienced the black screen problem on laptops for quite a
long time now. i could solve the problem with workarounds which worked for some
time, then the black screen problem came back again -- probably due to updates
(?). so i reinstalled older systems which are outdated by now (no updates).
---- and i waited ...
lastly, i could install without problems newer systems on 6 machines (asus
1215b, lenovo, acer, desktop computers), so i wanted to update the other
systems as well.
today i tried once again ubuntu 12.04, kubuntu 12.04, linux mint 13 both in 32
bit and 64 bit versions on the acer travelmate 5735Z -- still the same problem,
or worse than before: black after the boot screen even with live-cd (which used
to work before).
i cannot live with "workarounds" in such an important feature, especially when
they don't seem to fix things once and for all. ---- i need totally robust
systems for my users.
THIS problem makes my life really hard SINCE A VERY LONG TIME AND AFTER
EVERYTHING WORKED SO WELL. it is very difficult to explain people since 2011 or
so that i simply cannot help them -- after i talked them into using gnu/linux;
and it costs me too much time.
best wishes, topgyal
