I have installed gentoo from 1.4beta stage1, then rsync'ed, updated and installed new packeges several times. I have installed and built my own kernel from gentoo-sources (2.4.19). When I installed X, the server started by startx couldn't open mouse: (**) Option "Protocol" "IMPS/2" (**) Mouse1: Protocol: "IMPS/2" (**) Option "CorePointer" (**) Mouse1: Core Pointer (**) Option "Device" "/dev/psaux" (EE) xf86OpenSerial: Cannot open device /dev/psaux No such device or address. (EE) Mouse1: cannot open input device (EE) PreInit failed for input device "Mouse1" (II) UnloadModule: "mouse" (II) Keyboard "Keyboard1" handled by legacy driver (WW) No core pointer registered No core pointer Fatal server error: failed to initialize core devices I try to start gpm: gpm -m /dev/psaux oops(): [...path... gpm.c(956)]: Could not open /dev/psaux First of all, I have to remove /var/run/gpm.pid manually (this is gpm bug, I think). Then I can start gpm normally - no error messages. After that X can also open mouse normally. If I now quit X, kill gpm and try to start X again, it starts normally but mouse will not work. The pointer just stays in one place. So, gpm must be running for X to work. Other devices pointing to my psaux-mouse didn't work either. I don't know if this is related to devfs, but for me it looks like that.
1) To what bus is the mouse attatched ? 2) Did you compile in "input" support in kernel, and also mouse support under caracter devices (i think) ?
Created attachment 3674 [details] kernel config Here is my kernel configuration.
My mouse is a normal ps2 mouse in the ps2 mouse bus. It works well in Debian and Red Hat, which I also use in this machine.
Hmm. Does /dev/psaux exist ? On devfs it is a symlink ... the link valid ? Try using /dev/misc/psaux ? About gpm .. it just too braindead to clean the pid after itself.

Funky. Please attach your /etc/X11/XF86Config* files.
I don't think X config gives any information, but here is mouse section from XF86Config. # ********************************************************************** # Core Pointer's InputDevice section # ********************************************************************** Section "InputDevice" # Identifier and driver Identifier "Mouse1" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/psaux" Option "ZAxisMapping" "4 5" # When using XQUEUE, comment out the above two lines, and uncomment # the following line. # Option "Protocol" "Xqueue" # Baudrate and SampleRate are only for some Logitech mice.

A small promgram I extracted and moulded from gpm source: #include <stdio.h> #include <sys/fcntl.h> int main() { int *fdptr; if ((*fdptr=open("/dev/psaux" ,O_RDWR))<0) printf("Failed\n"); else printf("Succeeded\n"); while(1); } Here is a typescript again... a.out is that previous program compiled with just "gcc psaux.c". When I start it first time after booting the computer, it fails.

However, gpm starts every time after it has once started successfully, and X works only if some other program has psaux opened. I don't know anything about opening and closing devices, so someone else must continue on if necessary. Maybe this is kernel bug, but gcc3.2 is not for kernel anyway. Or maybe I just have some odd configuration and problem goes away with next emerge -e world or kernel recompilation. Btw, my mouse is Logitech optical usb/ps2 wheel mouse, if it makes any difference. And gpm is not really working, it flashes the screen etc., but it reads the mouse nevertheless.
I found the problem. I have keyboard in USB. When I tried that small program in Debian, it printed on console and into kernel logfiles: Timeout - AT keyboard not present?(f4) Probably due to different configs and/or version gentoo-kernel does not do this. in Debian and Gentoo this shows up in boot-time logs couple of times. However, in Debian mouse can be opened every time. When I moved the keyboard to ps/2, Gentoo started to work also. So this really seems to be a kernel problem. Devfs, input layer, something else?
Preempt/jiffies can cause wierdness like this. Care to try a vanilla kernel?
Yes, at last:) Vanilla works fine, no problems in opening /dev/psaux.
To get rid of a bad gpm session: gpm -k
Kernel issues.
