 |
|
After updating from vanilla 2.6.16_rc5 to _rc6 I was surprised to find my mouse cursor had vanished, though I could still use the remaining 'invisible mouse' to select things - it was just difficult to know where it was..
Anyway, it would seem the nv driver is responsible.
After changing xorg from nv to nvidia, and doing ctrl-alt-backspace things were back to normal 
I have just proved this by rebooting with the nv driver.
Bug 126121

Try adding
Option "SWcursor" "1"
to your Device section in your X config. |

Yes, that did it
But the problem only shows with 2.6.16_rc6, so I'm left wondering whether I should have had Option "SWcursor" "1" all along, or what?
Mvh
Edit: It has some odd affects though - my green mouse indicator changes to blue when over firefox window!

My guess is that you changed from NVidia GART driver to the kernel driver. Or the other way around. Check you kernel config for what you might have changed there.
Use
cat /proc/driver/nvidia/agp/status
to check wich GART you are using at the moment. |

No, I used my normal kernel update routine - "same procedure as every year Ms Sophie"
Mvh
Edit: | Code: | # cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Enabled
SBA: Enabled

which I have had for a year at least..
Edit: its still there with 2.6.16 - anyone else tried booting with the nv driver?

could it be that current xorg (hardmasked one) has the same problem? but it doesn't get fixed by adding swcursor option to xorg.conf.
any other ideas what could be done to fix it? |

| It's still not really fixed by using a software cursor instead of a hardware accelerated cursor. I wonder what the performance penalty would be? |
