Hi!
I re-compiled my kernel (2.4.31, Slackware 10.2), I patched some files in /usr/src/linux with bootsplash patch and I have re-compiled my kernel. I copied new System.map & vmlinuz to /boot. But know I can't use X. It sais:
It sais that with new System.map and vmlinuz but also with old System.map & vmlinuz.
Can you help me pls ?

could you please post the mouse section of your kernel config?

If the old kernel worked before it would seem strange that it doesn't work now, unless you no longer have the old kernel image, having overwritten it with the new one (didn't give the new one a different name).

It sounds to me like you just forgot to include mouse support. In the input device drivers section you need to incluse ps/2 mouse support support. And if it's a USB mouse, you also need to include mouse and hid drivers from the USB section.

X crashes :
I have usb mouse. And yes I do have /dev/mouse which is link to /dev/input/mice

Interesting...it doesn't appear to be a kernel issue at all. What are the permissions on the mouse device at /dev/input/mice and the /dev/mouse link? It could be that your user doesn't have enough permission to read and write to it. You might need to adjust the permissions on the device or add your user to a particular group.

A quick way to check if this is the case is to start X as root - just long enough to see if the device works. I know everybody says not to open an X session as root, but I find it to be a good way to quickly test for device permission issues.

I did it but it is still the same problem

Can you tell me how to fix this ? Is there any way to put back my "/dev/mouse".

This happened when I compiled my kernel. So, it means that it has something with it ...
