Has this ever been reproduced with another driver? Assuming the line number from
#0 fbCopyNtoN (pSrcDrawable=0x2d6eee0, pDstDrawable=0x2d6eee0, pGC=0x23dcf68,
pbox=0x7fffdccc4300, nbox=<value optimized out>, dx=<value optimized out>,

is accurate, it seems most likely that fbGetGCPrivate(pGC) returns NULL, which is most likely a driver problem (pGC seems allocated by /usr/lib/xorg/extra-modules/modules/glesx.so).
Or, if you're certain it's an xserver regression, please try and bisect it.
I'am not sure at all, I only looked at backtrace and supposed the problem is in xserver. I tried to look at the code but I was not able to recognize if the cause is originated from other step in the backtrace. The problem is that the upgrade to maverick upgrades xserver and fglrx too and is not possible to downgrade only fglrx. I will try again to use radeon open source drivers to see if the problem occurs too. I tried some time ago but X starts no more, it seems that in ubuntu there is a problem switching off the propietary driver. I use linux for work so I must be very carefull! Will try this weekend. In the meanwhile I filed a bug to amd http://ati.cchtml.com/show_bug.cgi?id=15 Anyway I expect xserver never crashes. The system became very unstable if a bad written application can crash the xserver (usually for an end user the gui is the system). There is a workaround patch that I can apply? i.e. adding some additional checks here #define fbGetGCPrivate(pGC) ((FbGCPrivPtr)\ dixLookupPrivate(&(pGC)->devPrivates, fbGetGCPrivateKey())) thanks for your investigation, If I can help somehow let me know, I am developer too but not an expert in xserver or drivers. sorry I missed to answer: >*Sigh* another 'upstream' report lacking critical information such as the >Xorg.0.log file... all details on the system are in the issue https://bugs.launchpad.net/ubuntu/+bug/659792, including xorg logs https://bugs.launchpad.net/ubuntu/+bug/659792/+attachment/1740027/+files/XorgLog.txt https://bugs.launchpad.net/ubuntu/+bug/659792/+attachment/1740028/+files/XorgLogOld.txt and conf https://bugs.launchpad.net/ubuntu/+bug/659792/+attachment/1740026/+files/XorgConf.txt https://bugs.launchpad.net/ubuntu/+bug/659792/+attachment/1740029/+files/Xrandr.txt https://bugs.launchpad.net/ubuntu/+bug/659792/+attachment/1740030/+files/glxinfo.txt If you need more infos, ask me I will provide you (In reply to comment #5) > Anyway I expect xserver never crashes.

>The X server can't do anything about crashes caused by drivers. is a segfault in a function in fbcopy.c, sometimes just checking for NULL refs , maybe, can avoid it. From my point of view xserver should should crash only if kernel crashes. Xserver is the kernel of gui apps, it should be stable. If a driver/module in the kernel crashes, the kernel survives, in the same way the xserver should survive to glesx.so. I can understand that not all possible problems can be avoided, but this should be the 'vision' for to compete with commercial OS. But those are only personal considerations! >I shouldn't have needed to go looking there, if an issue is to be tracked here, >all the relevant information should be available here directly. I agree, as said before: just ask :-) If the problem can only fixed in ati commercial drivers, I will try asap to switch to opensource drivers and wait for a fix in fglrx. Here is the backtrace using radeon opensource driver. It seems is not an issue of the driver.

that looks like an entirely unrelated bug.
strange, is reproduced exactly in the same way... a relation between the two situations should be... if you prefer I open a separate issue. (In reply to comment #16) > strange, is reproduced exactly in the same way... Which of the several ways described in this report exactly? > if you prefer I open a separate issue. There's already at least one report for that crash.
As said I can send a java program that reproduces the crash with both drivers
>There's already at least one report for that crash.
could you please give me the link, I searched '/usr/bin/X (xorg_backtrace +0x28) [0x45c448]' in freedesktop but as result gives only ths issue.
thanks
upgrading to ubuntu-natty the problem seems to be resolved! (In reply to Ötzi from comment #19) > upgrading to ubuntu-natty the problem seems to be resolved! Closing per comment #19, thanks. |
