x config issue

[guitarfella]

i think this started after i updated my nivida drivers

when trying to launch X window applications as root from a termial i recieve errors such as

cannot connect to X server and
no display name and no $DISPLAY environment variable

no problems with my user account though.. just root
how can i reconfigure x for root?

[Uranus]

It's better not to do anything in X as root. I think the command you are looking for is "xhost +root" - man xhost, I might be wrong about the exact usage.

your right about the X thing.. but id still like to have X for root anyway ; )

i recompiled my kernel to enable SMP, my system booted fine with the new kernel... but now the nvidia module wont load. error message include this when i try startx:

(EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module!

i tried to recompile the nvidia drivers, but it tells me its unable to load the kernel module 'nvidia.o'. it tells me to specify the kernel source path using the commandline option, which i specified exactly using --kernel-source-path=/lib/modules/2.4.26/build

it still returned the same error.

did i do something incorrect when compiling the kernel?

Why don't you upgrade to kernel 2.6? It's really worth it. Which distro are you using?

Kernel source path is usually /usr/src/linux

Maybe it's the source for the nvidia kernel

no no, nvidia was asking for the kernel source... i specified the /usr/src/linux path also... something is broken... i would have upgraded to the 2.6 but all i wanted was SMP for now...

is there a manual way to repair the x server? i mean, the drivers are already there

[Choozo]

As a regular user in a terminal, does this work for you?
$ xhost +
access control disabled, clients can connect from any host
$ su -
Password:
# <start your app as root>

m mm... i get

xhost: unable to open display ""


i have just noticed, when i boot my machine the agpgart module hasnt loaded. i get these errors

agpgart.o unresolved symbol kernel_flag_casheline
unresolved symbol smp_call_function
unresolved smp_num_cpus
insmod /lib/modules/2.4.26/kernel/drivers/char/agp/apggart.o failed
insmod agpgart failed


is this the problem? i compiled the kernel to enable smp but it appears to have created some issues. any ideas?

[Choozo]

Did you forget to 'make modules_install' after recompiling for SMP support?

[guitarfella]

nah i remembered. im gonna recompile the kernel... maybe i did forget something... if anyone thinks of anything else let me know :rolleyes:
