Mousedriver causes X to hang
Last modified: 2007-04-18 12:50:29 EDT
Description of problem: When starting the recent rawhide XFree86, it hangs before showing anything. Investigations show that /usr/X11R6/lib/modules/input/mouse_drv.o is the responsible part; when using the module from XFree86-4.2.99.3-20030115.0, things are fine. A speciality of my system is, that 'gpm' is used in repeater-mode (the laptop locks the keyboard randomly on unhandled mouse-input, so I am using gpm which keeps the FIFO empty): | $ ps x | /usr/sbin/gpm -m /dev/misc/psaux -tps2 -Rps2 Version-Release number of selected component (if applicable): XFree86-4.2.99.4-20030121.6 gpm-1.20.0-2 vanilla linux-2.4.20 kernel dev-filesystem XFree86-4.2.99.3-20030115.0 works fine

When using the working mouse_drv.o from XFree86-4.2.99.3, the log-file continues with: --- (II) XINPUT: Adding extended input device "Mouse0" (type: MOUSE) (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed (II) Mouse0: ps2EnableDataReporting: failed ---

Unfortunately, just tested the XFree86-4.2.99.902-20030224.1 with my DELL Inspiron and the system still hangs with a frozen mouse. The log file is similar to the one mentioned above. I did not get a chance to test 4.3.0-1 but probably the same. The culprit is probably the new dynamic ps/2 mouse driver.
Does this problem still occur on a Red Hat Linux 9 clean installation?
No. Things are working with 9 and beyond.
Enrico?
Currently I do not have a clean RHL 9 installation but a rawhide-based one with gpm-1.20.1. This setup hanged on 2003-01-30 and works fine now. I do not see the problem after downgrading to the shipped gpm-1.19.3 also, but this downgrade required a lot of significant changes and is not the same setup as before. Closing the bug...
Ok, thanks a bunch for the update!
