In this case, the bug should be called "SDL applications do not use PulseAudio on LTSP", because if I understand correctly, PulseAudio is the only way of getting sound to LTSP clients. IMO, this should be a global Ubuntu default, not just Edubuntu, as users are likely to experience problems (like I have many times) in this area. An SDL patch was applied to Intrepid in #216397 which greatly improves SDL's compatibility with PulseAudio. Setting the 'pulse' audio driver as SDL's default should definitely be done. -- tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp) https://bugs.launchpad.net/bugs/269082 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 269082] Re: tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp)
In case sdl checks for a local device this indeed would explain the probem ... LTSP starts a pulse daemon on the client and usually has the esd as well as the native pulse plugins installed server side. On login PULSE_SERVER as well as ESPEAKER (pointing to the client) get set in the session on the server and asoundrc creates a virtual pulseaudio device, so all sound output gets forwarded to the pulse daemon running on the client, be it esd, alsa or pulse sound. If the app tries to attach to the local device on the server but is told to actually forward all sound traffic on a higher level via the network there is indeed a discrepancy, since the found sound device is definately not the actual output device no matter which of the drivers you use. -- tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp) https://bugs.launchpad.net/bugs/269082 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Bill, thanks for such a quick response!

Can you try out one of the SDL demos that comes with SDL source, or perhaps another game (most of mine listed at http://www.newbreedsoftware.com/linux/ use SDL and are widely packaged, e.g., 'Defendguin' or 'Circus Linux!'). Of course, best to try something I wasn't involved in, to make sure it's not something _I_ am in a habit of doing that's causing this.

In response to an earlier comment, I can confirm that using the --nosound switch with tuxpaint corrects the issue with high CPU usage and failure to exit cleanly. Let's have some other people test this by running tuxpaint from a terminal with the following command: --- tuxpaint --nosound --- If this proves to help other LTSP users, maybe we can have some code to detect whether tuxpaint is being run from a thin-client terminal or not, and either disable sound accordingly, or fix the actual issue so sound can be used correctly.

[Bug 269082] Re: tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp)
I just installed Tuxpaint on my own LTSP server and launched with my thin-client (a LTSP-Term 1220PXE available from disklessworkstations.com and 100% supported by LTSP ) and will attach the following strace. The strace contains data from me simply starting Tuxpaint, drawing an "X" on the blank slate, adding 4 "Stamps" (2 of one Tux face and 2 of another), and then attempting to exit. When I exit, it asks me if I'm done, and I clicked Yes. It asked me if I wanted to save, and I said No. From there, the program locked up and I had to 'killall -9 tuxpaint' to close it. Normal 'killall tuxpaint' wouldn't work. Note that on my single LTSP thin-client, starting Tuxpaint took 55% of the CPU time, which is: $ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ stepping: 2 cpu MHz : 2210.121 cache size : 512 KB physical id : 0 siblings: 2 core id : 0 cpu cores : 2 fdiv_bug: no hlt_bug : no f00f_bug: no coma_bug: no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy ts fid vid ttp tm stc bogomips: 4423.66 clflush size: 64 processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 75 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ stepping: 2 cpu MHz : 2210.121 cache size : 512 KB physical id : 0 siblings: 2 core id : 1 cpu cores : 2 fdiv_bug: no hlt_bug : no f00f_bug: no coma_bug: no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy ts fid vid ttp tm stc bogomips: 4420.14 clflush size: 64 I hope this information helps.

[Bug 269082] Re: tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp)
I can only speak to tuxmath right now, and the interesting thing is that it does not seem so bad under a openSUSE ltsp server setup. I have tried to make it lock up and failed. The cpu cycles on the server stay relatively low (< 10%) when running. I cannot try on my ubuntu server anymore because it self destructed yesterday (funny smell then beeping motherboard - unfortunately it was a nice Athlon64X2 3800 that someone jsut donated - soo I'll have to fix it!) My server is a pentium 4 HT 3.2GHz Client is either a 1.4GHz - core 2 duo - reasonbly modern and fast and an IBM NetVista 2800 8364 Thin Client PII 266 MHz 128MB and both seem to perform fine (although the game speed on the netvista is slow even if I set --speed , but that is another issue) I am off to Germany for 2 weeks but when I get back I will see if I can get some Valgrind dumps etc... but yes on my ubunut server it would hog all processors 100% and refuse to shutdown on the client. Then I woudl sometimes kill it and it would no longer appear in "ps -A" but the server would still be showing 100% cpu utilization. -Eric -- tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp) https://bugs.launchpad.net/bugs/269082 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 269082] Re: tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp)
Hi, I'm the maintainer for Tuxmath and Tuxtype. Below is what I sent out yesterday to our dev list: "This is puzzling as the three programs don't really share much code (the menu stuff from Tuxtype was adapted for Tuxmath, and the Comet Zap activity in Tuxtype is an adapted version of Tuxmath, but that's about it). I hate to just say "it must be SDL", but it seems weird that three independently-coded programs would all create the same bug. >From reading the posts on the launchpad forum, it sounds like Tuxmath is using all the cpu cycles on the server when run from a thin client. It certainly doesn't do this when run on a single machine - a quick check with top on my desktop machine (amd64 dual 3800, 2 gig RAM) shows that neither tuxmath itself nor Xorg exceeds about 3% cpu. Of course it would use more on less powerful hardware, but I would expect a typical server machine to be able to run quite a few instances of tuxmath. I started up 10 instances just now on my desktop with no discernable effect on system performance. So, I don't have any immediate ideas. It might be helpful to know at what point in the program the resources all get eaten up (menus vs. game itself). Also, if the problem is 100% cpu utilization, it could be very informative to profile tuxmath with valgrind to see where all of the cycles are going. Tim is our resident valgrind expert and he might know how to do this." So, I think someone with a running network needs to get some more specific info about what is happening to bog the system down (cpu utilization vs. network saturation, where in the programs the problem is seen, etc) and ideally do some actual profiling. The programs do not tax the machine much at all when run locally, even on old, slow computers, so I suspect that something is happening in either SDL or Xorg functions related to the remote X session that is slowing the server down.

Re: [Bug 269082] Re: tuxpaint and other tux SDL driven apps slow down and/or freeze thin client terminals (ltsp)
Yeah, its an old problem that has affected LTSP since its inception on ubuntu, and is most likely related to SDL. As far as I can tell, it doesn't matter if Sound is on or off, it still brings down the network with 10 clients running it. There are also constant complaints of the exit screens hanging. I have not had a chance to compare it to other SDL driven programs, but I will run a few tests at a school Kind Regards, David Van Assche On Sun, Oct 12, 2008 at 7:45 PM, Caroline Ford <[EMAIL PROTECTED]> wrote: > http://osdir.com/ml/linux.ubuntu.user.edubuntu/2007-12/msg00182.html > says that there may be a sound connection.

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 On Fri, Sep 12, 2008 at 7:36 PM, Caroline Ford <[EMAIL PROTECTED]> wrote: > First questions from upstream - > > Which version of tuxpaint and ltsp is this?
