Package: tuxmath Hi Holger
Not sure of the versions involved. This seems to be a long standing bug (from googling around) that has only recently been submitted as a bug. Affects all three tux4kids programs. There is a suggestion that it is SDL related, but I've read that Google Earth works fine (which is bound to use SDL). https://bugs.edge.launchpad.net/ubuntu/+source/tuxpaint/+bug/269082 Ubuntu bug https://sourceforge.net/tracker2/?func=detail&aid=2161843&group_id=66938&atid=516295 Tuxpaint sourgeforge bug. --------------- Ubuntu 8.04.2 latest tuxpaint and tux suite apps... but it happens on all of them since at least a year... gigabit network... its definitely not the network... as even google earth and video streaming work fine without bringing as many computers down. We see the slow down on our dual xeon processor server with 16 gigs of ram with only 10-15 users starting up the tux suite. Its the most dramatic slow down and freeze of any software on the thin client systems, and we're trying to figure out why. here is a related bug post: http://osdir.com/ml/linux.ubuntu.user.edubuntu/2007-12/msg00182.html I can test some other non tux4kids SDL stuff if you like, but I know gcompris and childsplay work much better... Over the next couple days I'll try running a bunch of other SDL stuff and see how it fares compared to tux4kids stuff... anyway here are the version numbers: tuxpaint: 1:0.9.17-1ubuntu3 tuxmath: 1.5.8-2 tuxtyping: 1.5.15.dfsg1-3ubuntu1 If you need anything else, let me know Kind Regards, David Van Assche -------------- Ubuntu 8.04.1 Desktop (i386) 100MBit network/Thin-clients, 1GB link to LTSP server All thin-clients were at least PII 500MHz w/256MB RAM (older Compaq iPaqs) Latest version of Tuxpaint: --- [EMAIL PROTECTED]:~$ apt-cache show tuxpaint Package: tuxpaint Priority: optional Section: graphics Installed-Size: 388 Maintainer: Ubuntu Core Developers <[EMAIL PROTECTED]> Original-Maintainer: Ben Armstrong <[EMAIL PROTECTED]> Architecture: i386 Version: 1:0.9.17-1ubuntu3 --- This has been an issue since Gutsy (7.10). I recall talking with one of the developers a long time ago, he seemed to see something pretty basic as to at least speed things up a *bit* that had to do with SDL refreshing or something (it's been a LONG time so forgive me if I'm wrong). HTH, Jordan ------------ Has there been any progress on this. I have the same problem. Set up a ltps server running Ubunti 8.04.1 (With the Edubuntu add-ons) on a dual xeon 2.5GHz server. When I boot up just 1 thin client (IBM Netvista 300MHz w/128MB RAM) I can run everything else acceptable Firefox / open office / etc.. but when I launch TuxMath it grinds to a halt and uses 100% of one processor on the server. We have a dedicated 100Mb network. Thanks, Eric [EMAIL PROTECTED] ----------- Thanks Caroline -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
