Thumbs down What about nvidia's cursor problem ?

Hy,

CPU : AMD 64X2 3800+
MB : ASUS M2NPV-VM ( I use integrated graphic card and FB to 256Mo )
Distrib : FC6
Nvidia's drivers : 9xxx

My simple test :
With HWCURSOR => no cursor 1 time over 10.
With SWCURSOR => cursor OK

But when I run COMPIZ I need to use HWCURSOR because of graphic bug with cursor.

I'd already post this question, but the only anwser I get is "change your bios ... it's a common bug ..."

I want to know why nvidia's graphics card hide my cursor !

for nvidia-bug-report, see this post : http://www.nvnews.net/vbulletin/showthread.php?t=79828

Someone can explain me why this cursor disappear with hwcursor, and why with swcursor when I run compiz it's buggy.

thank to help me.

This sounds like a BIOS bug that I've seen others report. In most cases updating to the latest BIOS, and configuring the amount of RAM/frambuffer allocated to the GPU (in the BIOS) fixed the problem.

I've the latest version of my bios and the most important amount of FrameBuffer allocated to the GPU.

I mail this message to linux-bug@nvidia.com (some new information) :
Code:
Description of the Bug :

in normal use of metacity :
With HWCURSOR => no visible cursor
With SWCURSOR => cursor OK

when I run compiz :
With HWCURSOR => no visible cursor
With SWCURSOR => cursor visible bug with some graphics bug

My solution, a really boring solution :

1. run metacity with swcursor.
2. change xorg.conf file to hwcursor.
3. run gdm-restart.

Magicaly i can get a visible cursor with hwcursor's mode and with compiz it's ok too.

but when I restart my computer in hwcursor .... problem be back and i can't see my cursor.

sorry I know that is a bit harsh and unfriendly, but never forget NVidia is a company focused on making money.

- NVidia earned max. ~50$ with the chip they sold or even way less.
- You report a problem which only happens on your computer.
- The most likely reason why this problems happen is because your bios/motherboard seem somehow broken.

I am not sure wether its worth for NVidia to set an engineer for 2 days to workarround this problems ... just to get one happy customer more
