P750 on Ubuntu 9.10

Postby hessi » Sat Dec 05, 2009 1:20 pm

Hey,

until the upgrade to 9.10 my P750 worked fine, thanks to your work. Now, I can compile the driver without any errors, it just won't load correctly (magenta screen).

I keep getting the following error:
Code: Select all
...
(II) MTX(0): end of MTX Monitor info
(II) MTX(0): Monitor maximum supported pixel clock is 140 MHz
(II) MTX(0): Monitor Input Type = 1
(==) MTX(0): Using gamma correction (1.0, 1.0, 1.0)
(WW) MTX(0): Error #4 while loading Kernel Driver.
(WW) MTX(0):  Falling back to Local DMA
...
(WW) MTX(0): OpenGL is disabled on this screen because it is not hardware accelerated
GLX: WARNING! Server failed to enable support for direct rendering!
...


My system:
Kernel 2.6.31
xserver-xorg 7.4
xserver-xorg-core 1.6.4

It's horrible as it is. I cannot even watch a video fullscreen... So, ANY help is greatly appreciated!
Thanks.

Thanks, frank33! But unfortunately, this is with 1.4.7. ...

I have no idea, what that "Error #4 while loading Kernel Driver" means. Also, I don't know if the later OpengGL error is related to that. I'm totally lost on that...

Hey frank33,

many, many thanks for taking your time! unfortunately, my output of 'dmesg | mtx' is _a little_ shorter than yours:
Code: Select all
mtx: no symbol version for module_layout


That buffles me, because the driver compiled without any errors on my machine.

Helping with linux problems like this, is cool, :D

I think your error means the kernel module is built with different kernel source than your current running kernel.

either one of these;
/lib/modules/linux-2.6.xxx/source or build symlinks
/usr/src/linux symlink
/lib/modules/linux-2.6.xxx/kernel/drivers/mtx.ko

wohooo - that did the trick! thanks a lot, frank33!!!

here's what was wrong:
sometime ago i extracted the installer and then always used that directory to recompile the driver after kernel updates. i now deleted that directory, downloaded the installer again and let it create a new directory. everything works fine now!
