Hi,

just upgraded my main workstation (nvidia GeForce 6200) to 11.3 and I'm pretty disappointed by the gfx performance (in 2D! mode).

When switching virtual desktop I can actually see how the windows are rendered what I couldn't with 11.2 before with nvidia drivers.

I know this is proprietary stuff but still I was wondering if people have some hints to improve the performance.

Do you use KDE or Gnome? Does the problem exhibit itself only under one DE or under both? Vadym -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I use WindowMaker (and tried KDE shortly from another local user) and under KDE it's even more sluggish because of the enabled desktop effects. So it likely includes the 3D/OpenGL performance as well.

Example: CSS3 transitions in FF4b are much smoother on my slow laptop with Intel graphics compared with my powerful workstation having the nVidia card.

What's your Xorg doing? Is it chewing up 100% CPU while you're experiencing the sluggishness? Are you finding that the computer becomes completely unresponsive for 1 or 2 seconds at a time? This sounds a lot like what I experienced with my system with nVidia... on another system with intel graphics, the problem didn't show up at all and KDE4 works fine using default drivers and kernel. My solution for the nVidia/11.3 sluggishness problem was to bump up to the 2.6.35 kernel. Someone else has had success with booting with vmalloc=192M. I haven't tried the vmalloc boot parameter, but moving to 2.6.35 made a HUGE difference in my KDE4 performance.

This sounds like the problem the kernel developers had before with the 2.6.34-git8 and up. That's why they removed the git versions for 2.6.34, incorporated it in the 2.6.35 RC1 version and corrected the problem there. I have problems with 2.6.34-12 too with or without nvidia drivers in that the system is always unresponsive when switching desktops.. There are more problems with 11.3 so I have gone back to the 11.2 version awaiting the 11.4 version to correct all the quirks.

Just curious... why revert to 11.2 instead of simply using the 2.6.35 kernel in 11.3? Overall, once I "fixed" the kernel/Xorg issue and sorted the nVidia binary driver fight with Nouveau, 11.3 has been a nice upgrade over 11.2. I'm not facing any other significant issues, and it's generally better than 11.2. To be honest, if you wait on the next release to fix all the issues in the current release, you're going to be waiting a long time. Each release has had its quirks, oddities, and miscellaneous warts. I'm running 11.3 with KDE4.4.95 from Factory, kernel 2.6.35 from kernel head, and it's nice... very nice. Fast boot, video works well.. it's quite a nice release. I'm able to use it for my work on a daily basis (ie actually be productive with my job) and do leisure things like gaming (Wine 1.3 is working VERY well these days). KDE4.4.95 is working very well (two minor bugs I've bumbled on so far... one in dbus which caused problems with Dolphin... fixed by installing latest dbus.... and one in the KUpdateApplet... still not fixed).

Well, 11.2 works with all additions I made myself

That's a good enough reason :-)

Furthermore, Thunderbird is not working with even a unchanged install

I've been following this discussion on the other thread... and I cannot duplicate the probs. Thunderbird (using IMAP) is critical for me and my job. If it wasn't working, I'd notice immediately... not having any issues at all with it.

I expect that 11.4 is due in another half year or so, maybe when Thunderbird is fixed I switch to 11.3.

Eight months is the official cycle... so... March 2011 if my memory serves me correctly.

By the way: is resolution changing using CTRL-ALT-+/- working? It did not work under 11.3 with the nvidia driver installed. The thing is it is missing the mode settings in the xorg.conf file (so I copied the file from the 11.2 partition). I dislike the use of Kmag because it clutters my screen to much and is not practical when using the full 3360x1050 resolution for an application.

No more xorg.conf, so unless you create your own with all the modelines you want to use, Ctrl+Alt+ +/- does not work (at least not for me). Copying an old xorg.conf over is a recipe for problems in many cases... it does fix a few "corner case" issues with odd configurations, but not the recommended choice (from what I've read/observed) for most users. This is not an 11.3 issue.. this is a major change in how the whole X environment works. This is going to be an issue for you regardless of what Linux distro you use (assuming it's a recently released distro). xrandr is the way it's done now. Guessing.. would it be possible attach something to the old keyboard shortcut to fire off xrandr with the appropriate options to cycle up/down the possible resolutions? Maybe something for OpenFate? In my own workflow, I never cycle resolutions anymore... used to do it a lot, but since moving to TFT monitors, I just stick with the top native resolution... so it's a functionality I don't miss now that it's not there. The only time I fiddle with the resolution is if a game or full screen app did not exit cleanly and the resolution is stuck at some lower setting... eg 640x480. For the few rare times this happens, it's not hard to pop open the settings and change it back.

Yes, I noticed that the xorg.conf file does not exist anymore. Question, using nvidia-settings and saving the changes, can be done how, if I do not specify the xorg.conf file?

By default there is no xorg.conf file. You can create one - and nvidia-config does create a basic one), and add only the lines or extras you need to add extra functionality - eg adding modelines if they are required for some special case. Some people have had to add special tweaks and settings for unusual video cards, or custom settings for a special case monitor configuration... or the rare time when a monitor/video card is not autodetected correctly - it happens, but only in a very few cases (in my observations and experiences)

I use a lot of graphics and also do video editing. If I want to position things finely I need to switch resolution often. I can use the editor to show me a finer picture, but using the ctrl+alt+-/+ works way faster. I don't need it for other work. I will look into the "xrandr" you mentioned to see what it is and if it might be a solution.

This is probably one of those "corner cases" that has a specific need outside the usual stream of users. I haven't played much with xrandr outside of the defaults. Some people here on the list have talked about desktop icons they've created for restoring default resolutions. I haven't tried it, but... I'm guessing you should be able to use something like xrandr -s 1024x768 (for example) tied to a keyboard shortcut... I have no idea if this is a practical or reasonable solution for quick resolution changes... just an idea that popped into my head as a possibility... any one else reading can confirm... or have a better solution for quick resolution changes in these post xorg.conf days?

Maybe, if you use TFT monitors. But with CRTs it occurs frequently. The system can't guess correctly the size with the correct refresh rate without flickering. That is the screen size is set to 1280x960 with 75 Hz refresh rate (visible flickering) instead of 1024x768 at 85 Hz with much less or non visible flickering. It occured to me several times. Even worse if the system can not remember the corrected settings and you have to start with adjusting the display after each login.

This has been discussed on the list here along with solutions.

One more thing, I don't know about: All of the desktop/window managers work well with xrandr? IMO the default resolution should be set correctly by xorg and not by the window managers. I agree that the best is if the system can set things automatically; but it must be correct - no excuse. If it can't then tools for correction should be available. Like sax2 in openSUSE.

sax2 is no longer available/supported. Xorg has been changed to autodetect the monitors and set things up accordingly. If that doesn't work, you can still define an xorg.conf, or use xrandr commands to set the resolution. I didn't make the changes... I'm just using the results :-) C. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

4.4.95 (4.5RC3) is 3 weeks old now and we fixed a LOT of bugs for 4.5.0 final which will be out tomorrow.  I recommend waiting.

The repo is KDE:Distro:Factory in the OBS (for 11.3, zypper addrepo -f http://download.opensuse.org/repositories/KDE:/Distro:/Factory/openSUSE_11.3...) which currently contains 4.4.95 but will contain 4.5.0 when we throw the switch to enable the OBS to publish the final packages to the mirrors.

Cool. Looking forward to it. KDE4.5.0 will be a real flagship release of KDE4. The 3 week old 4.4.95 is working very well (minus the known bugs). The desktop changes and rework to the KDE Configuration window alone make it worth updating to 4.5. The re-grouping of the configuration options make a LOT more sense in the new layout, and some of the changes to how the rest of the desktop work are very very nice (eg how the system tray works). It's definitely worth installing final 4.5.0 release once it's out on Tuesday. :-) C. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
