gnome-terminal is slower with "nvidia" than with "nv"

[gabor]

hi,

if i open gnome-terminal, maximize it and open a text file, and begin to scroll in the file up and down, it's slow. by slow i mean it jumps to the next line in around 0.5 seconds.
this happens when using the newest (4349) nvidia binary drivers ( "nvidia" in XF86Config ).

if i switch to the xfree driver ("nv") it's a lot faster.

and if i switch to the 3xxx nvidia drivers, gnome-terminal becomes the fastest.

why?

i've read somewhere that gnome uses some calls that got rewritten when nvidia drivers went from 3xxx => 4xxx..

i tried RenderAccel=true, nothing changed.
i tried to switch to agpgart or to nvidia agp, nothing ..

Out of curiosity, what did you do to "set RenderAccel=true"? From the way you said that, it almost sounds like you tried to set an environment variable... is this the case?

[gabor]

no

from my XF86Config:

Section "Device"
Identifier "nvidia-generic"
Driver "nvidia"
Option "NvAGP" "1"
Option "RenderAccel" "true"
EndSection


btw. is renderaccel-true working for you? it helps?

[bwkaz]

I don't know about whether or not it helps (seeing as I don't use either Gnome or KDE, being a twm and Eterm person myself, I haven't ever seen what you're talking about happen), but I am using "RenderAccel" "true", yes.

I'm wondering if it isn't just bloat in gnome-terminal. Does Eterm do the same thing (if you have it), or xterm if you don't?

[gabor]

well, xterm is a lot faster than gnome-terminal when using the 4349 drivers.

the point is:

1. with 3123 drivers gnome-terminal is as fast (maybe faster) as xterm

2. with xfree's nvidia driver ('nv') gnome-terminal is faster than with the 4349 drivers.

i think this shouldn't happen.

of course i can go and fill a bugreport at gnome.org but i thought that maybe this is a driver issue.

before you ask:
i want transparency+utf8. that's why i can't use xterm(no transparency) or eterm(no utf8)

[bwkaz]

Yeah, Gnome will probably tell you it's a driver problem...

Don't know what to say.
