Blender isn't working properly.

shocks · #1 30th July 2009, 05:51 AM

I have installed Blender 2.49a. I am using F10 in Dell Inspiron 1525.

When I open Blender I will get blurred Blender window. Does anyone knows what is reason for it and how to fix this problem?

And one more thing Blender works fine in Vista.

I'm not sure what you mean by blurred, can you post a screenshot?

shocks · #3 31st July 2009, 06:47 AM

Hey how to past screenshot. I don't have access to any image hosting site what to do.

shocks · #4 31st July 2009, 07:04 AM

Finally I got some image hosting site for without sign up.

Below is image(s) of blender. See text in menu are blurred. I can't do anything with blurred menu like this.

Wow, that is messed up.

Ok, what video card and driver is the laptop using?

Can you try if disabling kms fixes it. I think i've seen screenshots (and bug reports) like this before.

It Intel inbuilt graphic I think its X3100. I haven't installed any extra graphic driver after F10 installation.

Oops, i'm extremely sorry i didn't elaborate. kms is kernel modesetting, which basically sets the video graphics mode in the kernel itself instead of xorg. Its a new feature available only in intel and radeon drivers currently. You dont actually need to know that. An overview is given at https://fedoraproject.org/wiki/Featu...nelModesetting .
Try the following to disable kms and see if it fixes ur problem:
Reboot your computer. While rebooting immediately after the bios screen press esc key, and enter the grub menu. There type 'c' to enter the command and in the second line (kernel ...) type 'e' to edit the command. Go to the end of the line and add 'nomodeset'. Then type 'b' to boot. Try to see if blender works properly. If yes u can make the change permanent by editing the same line in the file /boot/grub/grub.conf

after pressing "c" what command I should enter?

shocks · #10 31st July 2009, 01:46 PM

Ok i got it

shocks · #11 31st July 2009, 01:51 PM

Hey It didn't worked. Blender blurs as usual.

You are not the only one having this problem, almost anything that uses animated graphics does it to me. I have attached a couple of examples, the first is the emacs sign-on screen and the second is a youtube video.

I am also using the Intel driver, I think this is a problem with tiling but I don't know what to do about it, nomodeset has no effect whatsoever.

This is only one of a plethora of problems I have had since installing fedora11. I have spent more than a week trying to resolve video and audio problems, it is the worst experience I have had with linux since trying to learn linux on my own using slackware more than 10 years ago.

I am about to back up my home directory and reinstall fc6.

Which intel chipset are u having. I'm having 965M, and i have some other display problems ihttps://bugzilla.redhat.com/show_bug.cgi?id=507282 which go away on disabling modesetting. Also do you get the problem with compiz enabled or disabled?

EDIT: This bug seems to https://bugzilla.redhat.com/show_bug.cgi?id=505962

shocks · #14 1st August 2009, 05:50 AM

I am not pretty sure of chipset. It may be 965 as I found in net. Same problem occurs even when compiz is enabled and also disabled.

oldgold · #15 1st August 2009, 02:52 PM

Here is the answer.

If you don't have the file /etc/xorg.conf make it using system-config-display. If you don't have system-config-display go to a fedora mirror and get it. You will find it under development not releases.

Then turn off tiling as explained in this thread:
