Default SuSE 8.2 Performance troubles.

Details:

Athlon 2000XP, MSI M2Ml MB, 512 Meg Ram, Asus v7100 Geforce2 MX, 32 megs, DVI video card.

Fresh SuSE 8.2 install, all current upgrades.

Cheesy bench mark, no Nvidia driver, glxgears, 1280x1024, 20+ FPS.

Install the 4496 driver. Do the IGNORE_CC_MISMATCH thing, install proceeds without error.

Startx, get the Nvidia Logo screen, kde comes up.

There's no mouse cursor for about 10 seconds, and it goes away every few seconds, but does return. Things feel very slugish, but it works without crashing.

Start glxgears, it takes over 3 MINUTES to draw the gears. I let it run for 10 minutes or so, waiting to actually see them move, but no, they just occasionally flash, or randomly disappear.

Kill glxgears, it takes over 2 minutes to go away. The listed performance stats average 1 frame every 46 seconds.
(And this isn't full screen, it's the default glxgears startup size, which this box does 1146 fps without the driver! )

Uninstall the 4496 drivers, things return to normal, 20FPS full screen.

Any suggestions?

Any chance you could attach your XF86Config or XF86Config-4 file? There might be something you forgot to omit in the modules section.

Check that your videocard has an interrupt allocated (there may be a setting for this in the BIOS) and that it appears in /proc/interrupts

I enabled the IRQ in the BIOS, though it doesn't show up in /etc/proc:

(Edited.. Opps, I guess it does, hanging off the end of IRQ11)

CPU0
0: 54262 XT-PIC timer
1: 633 XT-PIC keyboard
2: 0 XT-PIC cascade
5: 0 XT-PIC ehci-hcd
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
10: 680 XT-PIC usb-uhci, VIA8233
11: 1792 XT-PIC eth0, usb-uhci, usb-uhci, nvidia
12: 9535 XT-PIC PS/2 Mouse
14: 19714 XT-PIC ide0
15: 4 XT-PIC ide1
NMI: 0
LOC: 0
ERR: 0
MIS: 0


My XF86Config is located here

Thanks for the help.

Try cat /proc/driver/nvidia/cards/0 instead.

cat /proc/driver/nvidia/cards/0

Model: GeForce2 MX/MX 400
IRQ: 11
Video BIOS: 03.11.00.07.00
Card Type: AGP

After turning on the interrupt in the BIOS, performance has improved to a whopping 1 frames in 12 seconds = 0.083 FPS

It may be that this card just sucks, WinXP install crashes with this card, according to MS, they suggest upgrading the cards BIOS, however, according to ASUS, this card is non-upgradable.

So it's been sitting on my desk for the last year, waiting for my Linux box upgrade.

I'd just go buy a newer card, if I was convinced that the driver would work with one...

Hmm, strange...

Sharing the IRQ should be no problem:

CPU0
0: 427769964 IO-APIC-edge timer
1: 1106352 IO-APIC-edge keyboard
2: 0 XT-PIC cascade
4: 254451629 IO-APIC-edge serial
5: 129958400 IO-APIC-edge AX.25 SCC
7: 2 IO-APIC-edge parport0
8: 8942032 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
11: 334999166 IO-APIC-edge serial
12: 177821 IO-APIC-edge HiSax
14: 7839166 IO-APIC-edge ide0
15: 7808723 IO-APIC-edge ide1
16: 539827453 IO-APIC-level sym53c8xx, usb-uhci, nvidia
17: 482369 IO-APIC-level Intel 82801DB-ICH4
18: 193079 IO-APIC-level usb-uhci, bttv
19: 89709522 IO-APIC-level eth0, usb-uhci
20: 19476633 IO-APIC-level eth1
23: 0 IO-APIC-level ehci-hcd
NMI: 0
LOC: 427767668
ERR: 0
MIS: 0

My card shares IRQ16 with a SCSI card and USB controller.
