Changing resolution scrambles display
« on: May 05, 2007, 02:50:24 am »

I'm using version 0.6.2 of UQM, and when I try to start with the opengl option (-o) or change the resolution in setup, the graphics 'scramble'.  Everything is fine if I stick with the standard resolution and don't use opengl.

I guess this is something to do with opengl.  My computer has an Intel GMA 950 - maybe that's the problem?

Do you have the most recent video drivers for your graphics card?

I should have also mentioned that I'm running this on Linux.  I'm using the latest version of Ubuntu, 7.04.  My xorg.conf file tells me I'm using the i810 driver.

Can you post your xorg.conf? My laptop (with an i855) also uses the i810 driver (on OpenSUSE 10.2, though) and UQM works fine.

Edit: And while you're at it, the outputs of xdpyinfo and glxinfo would also help.

Thanks. Looks like X.org is correctly configured, except that direct rendering does not seem to be working (which would cause OpenGL to fail).

I'd check with lsmod which modules are loaded (you should have one called i915, possibly i810) and check the X server log (/var/log/Xorg.0.log on my system) for error messages related to this.

If the necessary kernel module is missing try loading it with "modprobe i915" (as root) and restart X. If that's not it, please post the X.org log file and output of lsmod.

Interesting, it seems Feisty Fawn has AIGLX enabled by default. In my experience, this is not good for OpenGL software (last time I tried to use it, OpenGL apps either slowed down or crashed). You should be able to disable it by adding the following to /etc/X11/xorg.conf:

Code:
Section "ServerFlags"
   Option "AIGLX" "off"
 EndSection

Adding those lines to xorg.conf and restarting X didn't work unfortunately.  Maybe there's a way to stop AIGLX being loaded during startup?  I might ask about this on the Ubuntu forums.

It's annoying that AIGLX is on by default if this breaks other programs that use OpenGL.  I think the only reason this was done was to make it easy for people to try out compiz.

That was supposed to be it (according to the Ubuntu forum posts I found), but my OpenSUSE installation and your Ubuntu installation differ on this point so I can't really test it. Sorry.

No need to be sorry!  I think you've already gone beyond the point of support for UQM and are just being generally helpful now Smiley

I must have done something wrong before.  Now including those lines in xorg.conf does stop AIGLX from being loaded on startup (none of the AIGLX-related messages appear in the Xorg log file).  However, now when I run uqm, the display is no longer scrambled, but it sort of flickers and the main menu doesn't seem to respond to keypresses.  This happens even in 640x480, which worked before.  Oh well, I don't really need to play in resolutions higher than that, I just thought it would be nice to try them out.  Thanks for all the help.

Considering that your laptop display (or the Intel chipset driving it) is probably going to use the same bilinear interpolation to rescale 640x480 to the display's native resolution (1024x768, I guess) as UQM is using, I don't think the higher resolutions are going to look any better. However, if UQM isn't working, I suspect many other OpenGL games are going to have problems.

Anyhow, my last suggestion at this point is to also disable the composite extension. In Xorg.conf add:

Code:
Section "Extensions"
        Option  "Composite" "Disable"
EndSection

Edit: Just for kicks, I set up AIGLX and beryl on my laptop. I managed to get it running (at the expense of slowing things down quite a bit), but UQM (in fullscreen 1024x768 mode) started getting black rectangles of various sizes flickering on and off (works fine otherwise, though). Switching window manager back to kwin sorted that out. If your window manager is compiz or beryl, I suggest you switch to the default window manager for your desktop environment (metacity for Gnome, kwin for KDE, at least on my system; both have a --replace option to replace the current window manager).

I had something similar, of specific pixels in UQM flickering. It turned out to be the tv application I had running on another virtual desktop.
For some reason, pixels that had one specific colour (or perhaps several colours) were filled in with pixels from the tv. What mattered was the location of the tv application when it was hidden (switching virtual desktops just hides the window; minimising the window works too).
I made an image in that specific colour, and as I moved it around the screen I could see parts of the tv. It was kindof cool really; as if I had "x-ray glasses". Smiley

I got the same problem with the Radeon driver

    OpenGL renderer string: Mesa DRI R200 20060602 AGP 4x x86/MMX/SSE2 NO-TCL
    OpenGL version string: 1.3 Mesa 6.5.2

I could fix it by changing:

    glTexImage2D (GL_TEXTURE_2D, 0, GL_RGB, texture_width, ...
to
    glTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, texture_width, ...

in src/sc2code/libs/graphics/sdl/opengl.c

There seems to be a bug with glTexSubImage2D when src and dst format differ.

Ciao, ET.
