I am not quite as sure about this as I was, it seems that sometimes it survives the screen blanking at 10 minutes, but if it does survive, it usually locks up at 20 minute. >From the client console I have run... # xset -display :7 -q ... and this reports that blanking is done at 600 seconds with a 600 second cycle. Then the DPMS settings are for standby at 1200, suspend at 1800 and off at 2400. DPMS is enabled. I have tried... # xset -display :7 -dpms # xset -display :7 -q ... which shows that dpms is now disabled. But this doesn't disable the screen blanking, and the problem still occurs. Sometimes at 10 minutes, sometimes at 20. Or perhaps it's at 13 minutes or 18 minutes - it is impossible to audit this problem effectively. So perhaps the issue is with the screen blanking? I have tried setting the screen blanking to 100 seconds, which in theory should make the problem occur much more quickly. And sure enough the terminal failed after a couple of blankings. I now set the blanking to 9999 seconds and with dpms switched off... # xset -display :7 -dpms # xset -display :7 s blank # xset -display :7 s 9999 ... by my reckoning this should to all intents and purposes stop the blanking and power management. But it does seem counter-intuitive that the blanking could cause an issue of this type, unless this is a problem with xorg and rdesktop. Sure enough no screen blanking, but the rdesktop session hangs after about 15 minutes. So this issue is nothing whatsoever to do with power management. Has anyone else experienced random lock-ups with rdesktop? Any suggestions for debugging this problem? -- Chris Roberts +------------------+------------------+ | Distribution | Debian Etch | | LTSP Version | 5.1.10-1~40 | | Windows Manager | KDE 3.5.5 | | Kernel | 2.6.26-bpo.1-686 | +------------------+------------------+ | Distribution | Debian Lenny | | LTSP Version | 5.1.10-2 | | Windows Manager | KDE 3.5.10 | | Kernel | 2.6.26-2-686 | +------------------+------------------+ ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
