blender having problems

[thoth]

When I open blender it has all sorts of strange artifacts up at the top making it unusable. Has anyone else experienced this? Here's a screenshot:

Re: blender having problems

Hmm - What display driver are you using ?

I don't get artifacts with fglrx.

Are there difference between windowed - fullscreen ?

If you start blender in the konsole - any error messages ?

Re: blender having problems

Therein might be my problem. Right now its:

Driver "ati"


If I change it to:

Driver "fglrx"

it fails to boot X. I attempted to get the atidrivers installed but I might have mucked things up. the fglrx module won't load for me with this error:

modprobe fglrx
FATAL: Error running install command for fglrx

I've got a dell c610 laptop with an ati card in it that identifies itself like so in lspci:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY

I followed this guide:

to no effect. Any suggestions?

Re: blender having problems

Tried blender with ati (mesa) drivers. No garbage in the screen.

Only difference was in the konsole (ati):

:~$ blender
guessing 'blender-bin' == '/usr/bin/blender-bin'
Compiled with Python version 2.4.
Checking for installed Python... got it!
Xlib: extension "XFree86-DRI" missing on display ":0.0".

fglrx:

:~$ blender
guessing 'blender-bin' == '/usr/bin/blender-bin'
Compiled with Python version 2.4.
Checking for installed Python... got it!

About fglrx
I followed - Ubuntu Feisty Installation Guide
http://wiki.cchtml.com/index.php/Ubu...allation_Guide

Both methods work here.


Hmm - You wrote, that you have

ATI Technologies Inc Radeon Mobility M6 LY

. Have you tried this:

Re: blender having problems

Okay notice in that link you posted:

"Never ever ever EVER install fglrx. I'm speaking from experience. "

I did anyway, and fglrx still causes X to fail at startup, but his configuration does seem to work with "radeon" as my driver, and those added options. But I am still getting weirdness with blender. there is an error at the command prompt:

:~$ blender
guessing 'blender-bin' == '/usr/bin/blender-bin'
Compiled with Python version 2.4.
Checking for installed Python... got it!
Ignoring Xlib error: error code 169 request code 145
Ignoring Xlib error: error code 169 request code 145

I wonder what these mean? time to google around abit.

Re: blender having problems

You know what your problem with fglrx is? The version of the compiler used to compile the kernel module doesn't match the kernel you're running.

I wrote a nice little script to install fglrx which you can get here. (Read the help (--help) first, it's not the most user-friendly, unfortunately. Choose the ATI driver (not the repo) method).

Re: blender having problems

I sure do like that install script, however I'm still getting problems. I've tried a million solutions and I'm afraid one of those 'solutions' is still rearing its ugly head deep in my system. This script was by far the most elegant, but upon restarting after selecting the fglrx driver it comes up to a black screen. alt-F1 to get to the first console

cat /var/log/Xorg.0.log

And it gives an error about "No devices found"

and then a couple of other lines and it ends with "No Screens Found"

Any ideas?

Re: blender having problems

Well, thank you. I try to write all my scripts succinctly. Both of them.

Anyway, how about attaching or posting your xorg.conf?
