Hi,<br>I've done the following:<br><br>- Using the NV driver instead of the closed NVidia driver. <br>  Not tainting the kernel in any way and 3D acceleration disabled.<br>- Getting a backtrace of Metacity segfaulting. See links.<br>
<br>The crashes and artifacts (see quoted message below) still occur :(<br><br>Please see the following links:<br><a href="http://satl.com/segfaults_and_artifacts/metacity-bt.txt">http://satl.com/segfaults_and_artifacts/metacity-bt.txt</a><br>

Hi,<br>I'm having problems with the following components:<br> * GTK / Pango / Cairo<br>   - Fonts disappearing (partly or fully replaced by box symbols), <br>      segfaults, partly drawed widgets etc.<br> * 3d applications / games<br>

   - Hickups, segfaults etc.<br><br>The problems start to occur a while after using the X server. They do<br>not occur consistently. Usually when doing some user activity like <br>starting applications, editting fields or pressing buttons.<br>

Only Firefox, AMSN and intensive 3D applications crash almost instantly <br>with segfaults and/or assertions.<br>Programs like glxgears and xterm seem to work fine.<br><br>I have the following configuration:<br>Software: Ubuntu 8.04 with all latest updates applied<br>

Motherboard: ECS M825G, Chipset: VIA VT8378 [KM400/A]<br>Processor: AMD Athlon(tm) XP 2200+<br>Memory: Kingston ValueRAM 512mb DDR<br>Soundcard: Creative Labs SB Live! EMU10k1<br>Videocard: Nvidia GeForce 6200 (NV44A) with 256mb DDR at AGP 4x<br>

<br>I tried the following without any luck:<br> * Disabling the onboard videocard.<br> * Disabling the onboard soundcard.<br> * Increasing the AGP aperture.<br> * Reinstalling fontconfig and letting it regenerate all the caches.<br>

 * Regenerating the fontconfig configuration using debconf.<br> * Reinstalling Pango and Cairo from the Ubuntu repositories.<br> * Removing PCI soundcard and AGP videocard only using the onboard hardware.<br> * Trying another AGP videocard.<br>

 * Trying different xorg settings.<br> * Trying different RAM modules.<br> * Disabling compiz / glx / aiglx.<br><br>Also with the Ubuntu Hardy LiveCD this problem occurs. Windows XP seems to<br>work fine (but I do not prefer using that).<br>

<br>The most weird thing is that these problems still occur when using<br>different memory modules and/or videocards. Even the onboard one.<br><br>By reading the logs I also noticed Ubuntu Hardy is using an unstable<br>version of Xorg. I'm pretty dissappointed in their decision of this and<br>

I hope you still want to help me.<br><br>Please see the following links:<br><a href="http://companywise.nl/artifacts_and_segfaults/xorg.conf" target="_blank">http://companywise.nl/artifacts_and_segfaults/xorg.conf</a><br>
