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. I have a 7 schools ready to use Tuxpaint for the younger students, but this is preventing us from doing so in our LTSP environment. Please ask if there's any more troubleshooting I can do. ** Attachment added: "strace of tuxpaint launch described in comment" http://launchpadlibrarian.net/19399148/tuxpaint.strace -- 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
