Exclamation Since my last routine update monitor shuts down after entering user name & password


Ever since my last routine update (January) the monitor shuts down when I enter my user name and password. The laptop keeps on running, however.
Originally I could, before entering name and password, choose safe mode or restart without problems. (Safe mode did not solve the problem.)
Since a technician with limited Linux expertise has tried to fix the problem, the screen freezes at the stage of asking for name and password: I can neither enter them nor chose any other option, although the cursor still moves. The technician suggested that the graphics driver is not recognised by the updated software.

I use an Acer Aspire 5315
with Intel Celeron porcessor 540
up to 358MB Mobile Intel Graphic Media
802.11 b/g WLAN
with PCLinuxOS 2013

I am a Linux Newbie but need the system urgently to work with custom made lexicographic software for a project. Can anyone help please?

Making guesses here.
What I think is going on is for whatever reason EDID is not read or interpreted correctly by Xorg, as a result your screen protects itself against incompatible video modes and turns off. The answer how to troubleshoot this issue is probably in /var/log/Xorg.0.log. You can try and switch thru different video modes using (Ctrl)+(Alt)+(+) if this key combination is activated in your distro.

Thank you for your prompt response. The problem is that I cannot type in anything at the stage of the log-in screen, nor effect any action with the mouse.
One solution may be that Debian can be chosen at the earlier stage where the distro must be selected. The software was developed with Debian before it was replaced by the more user0friendly PCLinuxOS. But I lack the expertise to use Debian.
So I will have to find some local assistance (presently Cape Town) to consider your recommendation.

Use some other Linux to boot and look at your Xorg log, SystemRescueCD is great (can be put to USB stick, too), GRML will do, practically any linux CD/DVD will do that allows you to get to the shell.

Problem solved

Thank you for your assistance offered, Emerson!
I found a local IT architect who fixed the problem. He got into the settings via "mcc" and fixed various corruptions; mainly, he replaced the installed driver with a VESA driver.
Thanks again!
