Glchess uses ~100% CPU while doing nothing

[Bui Arantsson]

Binary package hint: gnome-games

When I run glchess on Lucid Beta 2, it uses up 100% of my CPU even when it is not doing anything, regardless of whether I am playing against the computer or human vs human.

this was reported with beta, is this still an issue with latest packages there? which video driver are you using?

apport information

[Shaji N V (nvshaji)]

I am facing the problem with lucid (uptodate) using nvidia kernel module.

[Bui Arantsson (bui-foss)]

Yeah, the problem is sadly still there in 10.04 final:(

[Bui Arantsson (bui-foss)]

forgot to add: I am using the Intel video driver.

[Pedro Villavicencio (pedro)]

Wow that was fast, let's set this to Confirmed, thanks for the comments.

[Robert Roth (evfool)]

By the description this seems to be the same as #365740. High processor usage in glChess... could this be the duplicate of that?

[Shaji N V (nvshaji)]

I can help debug the problem, but how do I get a dbgsym enabled package for glchess?

Upstream bug is https://bugzilla.gnome.org/show_bug.cgi?id=578130

[Pedro Villavicencio (pedro)]

Thank you for sent it upstream.

I use Ubuntu 10.04 and these programs: glchess 2.30.0-0ubuntu6, gnuchess 5.07-7, sjeng 11.2-8
I also have this bug with glchess and these engines: gnu chess, sjeng.
All it's ok with these engines: crafty, toga II, phalanx, glaurung, hoichess, fruit.

[Octavian Stolnicu (totonebadass)]

I have the same problem in 10.10. Using radeon video driver (ati x600).
Using crafty engine. The cpu usage goes to 95% while playing and non-playing (between games, before game, after game).
 I have noticed that the cpu usage sometimes drops to around 3% but i have not been able to figure out what triggers it.

Same problem here too.

I have two computers. (desktop and notebook)
Here, the problem occur only in notebook.
