Hi,
the main problem here is that you are reporting the problem against
"general", since that will probably not lead to the bug being acted upon.
"Hewlett Packard Pavilion g6 2239-sr reffered as "laptop" later
after clean Debian stable install (with Xfce DE, but i assume it's not
important as it has problems with most if not all DEs)
and instalation of "firmware-linux" metapackage and tlp
What does "tlp" mean?
The outcome was that it rendered system unusable when booting on battery
power, as it freezed system on Log-in screen with slight graphical
glitches appearing on screen like broken mouse cursor/pointer/arrow as a
mess of ASCII characters (not letters but symbols rather) and the part
of input field(s) becomes a little bigger than another making a slight
aliasing effect
* does the problem not happen when connected to power?
* when you switch back to CTRL-ALT-F1, do you get to the login prompt?
I assume that the problem is with the graphics system. Can you please find
out what graphics driver is being used? Have a look at
/var/log/Xorg.0.log.
Do you see any problems reported there?
Once you have determined what graphics driver is being used, then can you
please find out to which package that driver belongs and reassign this bug
report to the relevant package? Better yet, make a new bug report against
the respective graphics driver package, since that should collect a lot more
informations and add them to the report. Once you have created the new bug
report, then please merge this bug report with the newly created bug
report.
Did you google around for the type of your laptop and the graphics chip
whether there are maybe other bug reports and or solutions?
