Terrible preformance after upgrade

[jayseejc]

Intel graphics preformance suck after the upgrade from 12.04 to 12.10. This is especially noticible when using the desktop cube effect, which ran fine under 12.04. Has anyone else experienced these issues? Have you found a fix?

[Snowhog]

Disable the Blur effect.

[jayseejc]

Didn't help.

[whatthefunk]

Check your graphics drivers. My guess is that you still have an old driver installed.

[jayseejc]

Updating my graphics drivers didn't help, and in fact broke more things. I'd like to note that this problem happens from a live cd, on a fresh install and in my upgraded install

[Teunis]

What hardware and which version of driver are you running?

[jayseejc]

Not sure how to tell which graphics hardware I have. All i can tell you is i have a toshiba satellite p870, which includes both nvidia and intel i7 integrated graphics. Also don't know how to tell which graphics driver version I'm using.

xserver-xorg-video-intel + dualscreen=Some KDE-Effects are slow

Hi there.

+1: Same situation for me.
After updating to 12.10 the graphics performance with the onboard intel-graphics is with some kde animations very slow.
This includes the minimize and maximize animation and the turn-off darkness.
I found some interesting effects:

• The graphic peformance decrease dramatic with two screens
• Some animation work well with two screens (i.e.wobly Windows)
• 3d Games and 3d-tools work well and performant
• Enabling vsync with dual screen gives artefacts in animations at 1/4 of the height from top of the first screen an 1/4 of the height from bottom of the second screen

It is not a problem of old drivers, they worked fine in kubuntu 12.04. The problems occured after updating.
You can get rid of that problems by switching to xrender. But this is a kind of give up, because xrender renders the 3d-effect only with the cpu. Some effects (like blure) do not work and a vsync is not possible.

I hope I could help you.
Is it possible, that someone reproduce my findings or am i alone?
Problems must be in KDE. Has someone a good tweak?

Yours

nVidia Optimus is not completely operational yet in Linux, although much progress has been made in the last few months. Please post the contents of /var/log/Xorg.0.log here, I'd like to take a look at yours. We can learn what drivers are loading.

It might not be KDE.

Ubuntu Quantal upgraded to Mesa 9 in August, which is during the development cycle. Only very recently have reports been coming in to KDE about performance and rendering issues. The thinking is that a late regression might have crept into Mesa or X right before Quantal release. The Ubuntu X team and the Kubuntu developers are investigating.

Not sure how to tell which graphics hardware I have. All i can tell you is i have a toshiba satellite p870, which includes both nvidia and intel i7 integrated graphics. Also don't know how to tell which graphics driver version I'm using.

My Xorg.0.log:
{...log text snipped...}

X sees only the Intel chip in your computer, not the nVidia -- the log shows no attempt to load nVidia drivers. Actually, the log looks downright boring -- that is, everything appears normal

A number of possible solutions for your performance problems come to mind. I'd like to start with a configuration change that will enable Sandy Bridge New Acceleration (SNA) in your driver. Currently, it's defaulting to the older UXA.

Please create the file /etc/X11/xorg.conf and place the following in it:

Section "Device"
        Identifier "intel"
        Driver "intel"
        Option "AccelMethod" "sna"
EndSection

Reboot your computer. Once you're back to the desktop, open a command prompt and run

grep -i sna /var/log/Xorg.0.log

You should see a couple lines that indicate SNA mode is activated. Do some stuff for a while, and let us know whether you notice any graphics improvements.

Since it's not fully implemented wouldn't it be easier to disable one of the video chips in the BIOS (or UEFI)?

I can't activate the desktop cube on my Dell Inspiron n5010 with intel HD graphics since the upgrade.

Plus, i can't run a virtual android device from the SDK. guess it is related to the graphics

Since it's not fully implemented wouldn't it be easier to disable one of the video chips in the BIOS (or UEFI)?

I assume you're referring to Optimus?

My ThinkPad T520 is equipped with Optimus: nVidia 4200M and Intel HD3000. When I configure the firmware for integrated graphics, the HD 3000 is enabled and the 4200M is disabled. The kernel loads the i915 module and X loads the Intel driver. When I configure the firmware for discreet graphics, the HD 3000 is disabled and the 4200M is enabled. The kernel loads the Nouveau modules and X loads the Nouveau driver. When I configure the firmware for Optimus, the kernel loads both sets of modules and X loads both drivers. But Nouveau doesn't reliably work with vga-switcheroo yet, so the HD 3000 is actually driving the graphics output.

In Jayseejc's Xorg log, only the Intel driver is loaded, which leads me to believe that the firmware is already configured for integrated graphics only.
