I have been using both gpm and the ACPI patches for a while now and until recently everything was going quite well. I run RedHat Linux 7.2 with kernel 2.4.17 from kernel.org with the ACPI patches version 20020225, and XFree86 4.2.0. Up until a short time ago I was running gpm version 1.19.6 and then upgraded to gpm version 1.20.0, now I get a strange problem where I lose mouse and keyboard if I switch consoles, but only if I run with gpm 1.20.0 and ACPI 20020225. I switched to gpm 1.20.0 along with some very nice patches, from Peter Berg Larsen, to the synaptics driver since it gives me almost the same features as the Windows driver for the touchpad. Here is a summary of what is happening; - Start the system normally to init level 5 (X is running), it does not matter if I log in and start gnome or KDE, or just stay at X login screen - change to console mode using <CTRL><ALT><F1> - if you change back to X using <CTRL><ALT><F7> then X hangs part way through redrawing screen. There is no mouse or keybaord. - X is using over 99% of CPU and the only way I have been able to clean things up is to ssh into the notebook and restart the system. - I can SysRq-B and reboot, but the ext3 filesystem doesn't like this. Oddly enough if I start another X session on display 1 <CTRL><ALT><F8> and us it and never switch to the session on display 0, everything is fine. I can switch between console and display 1 with no problems. I have only found this problem with gpm version 1.20.0, this does not happen with gpm 1.19.6. I have also verfied that this same problem happens if I configure gpm for a standard ps/2 device and not the synps2 device I normally use. I have also found the following; - start with identical kernel 2.4.17 with no ACPI compiled in and everything is fine. - start with kernel 2.4.9-21 and acpi 20010615 compiled in and everything is fine. - have tried using X with direct ps/2, not using gpm, and everything is fine. - have tried gpm 1.20.0 with and without Peter's patches and the results are the same. - have tried gpm 1.20.0 using ps/2 instead of synps2 protocol and results are the same. - have tried starting to init level 3 and logging in and then using startx, but this gives the same problem. I am still doing some tests to determine why this is happening, and will probably try a newer ACPI patch to see what happens. Has anyone else found similiar problems? Is this a problem with gpm or ACPI? Any assistance in this matter is greatly appreciated - Troy Schultz
