An issue with video

[Member Ninho]

I’m using an older, “classical” system – nothing fancy (Pentium III, DELL/Intel Mobo, CRT display unit). Under certain rare circumstances, which I found by accident, the GUI display becomes “funny”, on screen characters are somewhat blurred with a strange blue-greenish hue, difficult to read. Makes one think of a color “plan” not being quite right, or some sort of inappropriate antialiasing applied… Something gone wrong for sure !

Circumstances which have caused this to happen so far and can be recreated : – running DOSBOX ; – also, resuming after light suspension (screen saving) …

In each case, ending/restarting ICEWM hasn’t been enough to cure the defect. Closing & restarting the X-session does result in proper reinitialisation of the display.

Ideas for a possible resolution ? Here I’m copying the report from Control center – System information – Display, in case it helps. Of notice, it says using a “VMWare” driver to rendrer OPENGL, which if true sounds like a poor man’s hack : maybe that’s the problem, or part of it… Otherwise I’m out of clues… TIA !

Any ideas ?

=============
additional details merged from another topic:

I do not have an issue with video in DOSBOX, indeed I am not even remotely interested in running a DOSBox.
It just happen the recurrent problem with the video driver going mad appeared last time after trying DOSbox (video IN DOSbox itself had no problem!)
I had the exact same problem yesterday when the computer came out of sleep with the video broken.
Symptoms – fuzzy characters, funny colors; I suspect the video driver (VMware, yes, really?) is not right for my ATI Radeon video card (32 Meg DDR).

What have you searched?
What have you tried, toward solving the problem?

Do some legwork.
Come back a start a fresh topic when you’re ready to provide a topic title less vague than “An issue with video”

Page1 results from websearch “dosbox video problems” would provide a starting point ~~ plenty of leads

The machinetype affects the video card and the available sound cards. -noconsole (Windows Only). Start DOSBox without showing DOSBox Status Window (console). Output will be redirected to stdout.txt and stderr.txt. -startmapper. Enter the keymapper directly on startup. Useful for people with keyboard problems.

Some possible fixes:

Use / instead, or ALT-58 for : and ALT-92 for \.
Change the DOS keyboard layout (see Section 8: Keyboard Layout).
Add the commands you want to execute to the [autoexec] section of the DOSBox configuration file.
Open the DOSBox configuration file and change the usescancodes entry.

I have thought about opening this back up. You did describe the problem, and some basic solutions and tests indicating that you can reproduce the problem, as well as providing some system information.

However as you have noted after viewing the system information you may have the incorrect driver. As noted by skidoo there is information readily available to specify the driver to use for X. (boot cheats, xorg specification, etc). Granted this is a new forum, there is still the ability to search the old one. Especially after skidoo put loads of effort into making an archive specifically for situations like this. My “recommendation” would be to search up here, and the old forum / archive for how to change X drivers. Really based off what you posted that is all that can be said.

“vmware […] surely that can’t be right”
^—– could be correct. Lotta commercial entities write & contribute drivers. That openGL driver may be generically applicable to various brands of cards.

“is not right for my ATI Radeon video card (32 Meg DDR)”
^——- if you’ve already posted the output from inxi command in a different topic, paste it again here.

Here’s another websearch, using another of the details mentioned within your earlier post.

(reading [SOLVED] among the top search results is a promising indicator. Fingers crossed)

Hello,
it seems as though you are using the vesa driver. You may have better performance trying to use the radeon driver as based off your graphics card model and the following debian wiki/links.
