Trouble w/ kernel 2.5

[gsfgf]

I emergerd the development-kernel. It seems to need keyboard drivers.
I have serial i/o, Keyboards, and AT Keyboard built into the kernel. However, my generic PS/2 keyboard won't work. i8042 keyboard controller(do i even need it?) won't build. I'll make bzImage and the it'll say the kernel is up to date and i8042 keyboard controller won't be selected next time i run make menuconfig.

Also, when i boot w/ my 2.4 kernel, x won't start. It gives me undevined symbol errors in glx libs. I can use x w/ option glx cdommented out and the nv driver instad of the nvidia (accelerted) driver. I re emerged nvidia-kernel and nvidia-glx.

i updated to the 1.4.19-xfs kernel, but i have the same problem. emerge nvidia-kernel depended on gentoo-sources, but still 2.4.19.

From my attempts for trun 2.5:
yes you do need i8042 and the AT keyboard. But more important: I only succeeded in getting it right after I started the building process of my kernel with make mrproper.

For nvidia: you have to make sure the symlink /usr/src/linux is pointing towards the right kernel version you want to have it built for.
Also, pay attention to the fact that re-emerging nvidia-kernel can also remove the currently installed version of nvidia-kernel (autoclean!) .
Only version 1.0.3123-r1 works with 2.5.

I emerged nvidia kernel for my 2.5 kernel and compiled it by hand (after changing the symlink) for my 2.4 kernel.

However, this post (very interesting reading) suggests you can also use the emerge command twice to install nvidia-kernel.

BTW glxgears run 10% faster under 2.5

Thanks for the plug, but I suspect that autoclean will thwart attempts to emerge it twice, and it may never have worked in the first place. Maybe you could try something tricky like emerging it for 2.5, temporarily stashing the 2.5 /lib/modules directory somewhere safe, emerging it for 2.4 (letting Portage delete stuff in the 2.5 modules directory if it wants) and then replacing the 2.5 modules directory with the backup you made. Tough to say if that's easier than compiling one set by hand or not.

I wonder if there's a cleaner way to do this in Portage. Not that the situation comes up very often, but...

Actually,
it does come up for lm_sensors, alsa (not with 2.5, but usually), NVidia-driver, VMWare and anything else that may be kernel-related.

I did try to backup some modules from /lib/modules, but did not get it to work right away, and decided to compile them by hand (same for LM_sensors).

So I did spend some time searching for a cleaner way for this as well, but without succes. Maybe a nice enhancement request
(on the other hand, clever people should keep their development stuff on another partition...)

note: i haven't installed nvidia drivers under 2.5, just 2.4

ok, i have 2.5 running.
2 probs:
1) nvidia drivers still don't work. i did change the /usr/src/linux sumlink to point to the 2.5 dir
2) my mouse doesn't work. when i startx it says /dev/mouse: no such file or direcotory. when i ls /dev mouse shows up. when i ls /dev/mouse or /dev/m* it says /dev/mouse: no such file or directory. i have mouse, ps/2 mouse and inport/ms/atixl busmouse in the kernel. (my mouse is protocol imps/2 in xf86)/

Just checking

[gsfgf]

where does your /dev/mouse point to
mine oints to /dev/misc/psau which doesn't exist.

/dev/psaux.
This is also what XF86config points towards.

[gsfgf]

Got it.
i needed the mousedev option enabled.

NEW SYSTEM:
My imps/2 mouse no longer works correctly in X. When i move it the cursor jumps all over the screen and X recieves clicks all over the place.

The ps/2 touchpad (which never worked before w/ the imps/2 driver) now works fine. hmmm
