much better...but I'll only consider it usable once I can use kde 4 (without compositing) on the lowest powermizer speed bracket, though I reckon thats more due to the crappy acceleration arch in X than anything nvidia can do (apart from increasing powermizer response time, which in my books is still too sluggish)...

for me 177.70 is working great! finally! everything is smooth again on my 7800GTX. The only problem i found, is that when setting IPP to 2, after a bit it falls back to IPP=1. I found the following kernel msg:

Aug 29 01:33:10 [kernel] NVRM: Xid (0001:00): 13, 0000 80019700 00004097 00001900 00000000 00000800
Aug 29 01:33:14 [kernel] NVRM: Xid (0001:00): 55, L1 -> L0

Aug 29 01:33:19 [kernel] NVRM: Xid (0001:00): 55, L0 -> L0
Aug 29 01:33:19 [kernel] NVRM: Xid (0001:00): 13, 0000 80019700 00004097 00001900 00000000 00000800

Not that i can really complain anymore, but i was wondering what that could be. I'll add a bug report and more info as soon as i can..

thanx

Is "export KWIN_NVIDIA_HACK=1" still needed? Are there any performance gains when using it (haven't noticed anything myself)?

Default Re: 177.70 (BETA) for Linux discussion & problems thread

Greetings,

The only problem I encountered so far with 177.70 (as well as with all previous 177.* beta drivers) is related with CoolBits: as soon as I try to touch to the GPU or memory clock settings (even by *underclocking* them), the driver crashes the computer (blank screen, keyboard unresponsive, sshd unresponsive, no disk activity) as soon as I press the "Apply" button.

My setting is:

PCI Express 16x Nvidia 8800GT 512Mb (Twintech 8800GT Zalman).
Gygabyte GA-EX38-DS4 motherboard.
4Gb RAM (DDR2-800, not overclocked)
Q6600 Core2 Quad CPU overclocked @ 3.5GHz and 400MHz FSB (100% stable: runs SETI@home optimized app 100% of the time on the four cores without any crash neither any math error ever).
Linux 2.6.25.16 (vanilla kernel)
Mandriva 2007.1 (32bits OS - Xorg 7.1)

With the current release driver (173.14.12) I do not have such an issue and can enjoy a nice 674MHz (GPU)/1054 MHz (memory) overclock of the 8800GT with 100% stable operations and quite cool a GPU (under 50C in all circumstances).

thanks in advance
This makes it harder not easier ... each problem in a separate thread is easier to spot and to track than some random post in a long thread.

Scrolling in FF seems much better with 177.70, but text rendering performance regressions are NOT fixed on my 6600GT:
Code:
Subpixel=ON; IPP=2
gtkperf -a -c 100:
...
GtkDrawingArea - Text - time: 72,07
...
Code:
Subpixel=OFF; IPP=2
gtkperf -a -c 100:
...
GtkDrawingArea - Text - time: 3,79
...
Code:
Antialiasing=OFF; IPP=2
gtkperf -a -c 100:
...
GtkDrawingArea - Text - time: 4,10 (weird, gray AA faster than no AA at all?!)
...
Returning to IPP=1 makes things go fast again, but xrender performance (naturally) returns to <177.xx, so again sluggish ff, kde4, etc...
Code:
Subpixel=ON; IPP=1
gtkperf -a -c 100:
...
GtkDrawingArea - Text - time:  2,94
...
Strange, but in real-life apps (with IPP=2) subpixel rendering seems not as slow as in gtkperf, but still sensible slower than in <177.xx drivers.
Also, with the new beta, Konsole from kde3 occasionally (not always) becomes slow as hell regardless of IPP setting, i can't understand the source of this.

Feedback about 177.70.

Here (see signature) results are as follows:
* hibernate broken completely (black screen after resume), however worked fine with 177.13
* IPP=2 gives better results in gtkperf than IPP=0
* IPP=0 gives a lot better scrolling in firefox than IPP=2 (when IPP=2, scrolling starts really slow then it speeds up but never matches IPP=0)

My observations:
- Plasma is now faster but not smooth (still takes 100% CPU), but might be KDE-related
- I think the 3D performance increased

works fine just as before.

note that if you have an issue with this driver - post to a new thread or on regarding the same issue like the devs asked. giant threads covering multiple issues may simply be ignored.

Hello, I am very thankful to the devs of nvidia-drivers, they are doing a big piece of work putting together a driver to work in many distributions and architectures. It is not as easy as it seems. Thank you very much.

I use kde-svn with nvidia-drivers, full compositing and all effects. It works good, the performance is worth the risk of beta testing, and the ncurses issue seems to be fixed; don't know if that was voluntary...

The Blur effect of KWin compositing has a poor performance. I hope the KDE devs and you can find the cause.
