Bug 133645 – dosbox makes Xorg consume over 70% of the CPU power

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Attila Stehr 2006-05-17 15:06:27 UTC]

I'm not sure if this is really a bug, thus I set "devs only". Please make it public if you think that it is a bug.


Well, for a week I can not use dosbox-0.63 satisfactorily since when it's running - even only showing the dos command line - the X server consumes above 70% of my CPU power. I attached an image containing screenshots to picture the difference.

I reemerged dosbox-0.63 -> no effect.
I can't emerge dosbox-0.65 because of bug #128435.

X works fine with other applications and I have no (EE)s in the log file. I didn't come across a similar behaviour regarding other applications.

I didn't think the JPEG will look that awful (almost unreadable) ... so here comes the PNG.

Please don't restrict bugs without any reason...

[Comment 4 Attila Stehr 2006-05-17 15:55:24 UTC]

um ... I thought I did it for a reason:

s/any/a good/

Attach your ~/.dosboxrc file as text/plain please.  So far, it seems like another amd64-only thing.  Works fine on x86.

[Comment 6 Attila Stehr 2006-05-18 15:23:58 UTC]

hum, I haven't got such a file...

atti@magic ~ $ ls -al ~/.dosboxrc
ls: /home/atti/.dosboxrc: Datei oder Verzeichnis nicht gefunden
atti@magic ~ $

magic atti # date
Fr Mai 19 00:16:36 CEST 2006
magic atti # locate / -u
magic atti # locate ".dosboxrc"
magic atti #

Do I need such a file?

[Comment 7 Attila Stehr 2006-05-18 15:35:02 UTC]

At last I found a workaround for successfully emerging dosbox-0.65 (see bug #128435).

Therewith the problem I described in this bug report disappeared. Should I give this bug a different state now ... like "wontfix?

By the way, I still do not have a ~/.dosboxrc and it looks like this no problem. Is it?

[Comment 8 Mr. Bones. (RETIRED) 2006-05-18 19:46:12 UTC]

only if you want non-default behavior.
