On the X/mesa side of things, this is really a dupe of bug 555641, which is basically a wishlist for upstream's Shatter functionality (which allows building a screen up from multiple texture buffers, each of which would fit within the gpu's texture limits).
However, that functionality is a _long_ way off. In the mean time, I think compiz needs to include a check for the maximum texture size compared with the resolution during boot. This may be a compiz regression, since it used to do this in the past, c.f.: http://ubuntuforums.org/showthread.php?p=4166024 """ I am running an integrated ATi XPRESS 200 Series video card. Here is my COMPIZ : Checking for Xgl: not present. ... Checking for Composite extension: present. Comparing resolution (1440x900) to maximum 3D texture size (2048) Passed. ... """ So I will leave the compiz task open here. Possibly it's a dupe of other bugs, this is not an uncommon problem. I'm going to close out the mesa task as Won't Fix, since it's definitely a _valid_ issue, but not something we can really fix on the X side easily, rather than marking this as a dupe, since some work does need done on the compiz side here. (Btw, there may also need to be similar checks in gnome-settings-daemon if it is used to change monitor layouts while compiz is running, however that's a separate problem...) ** Changed in: mesa (Ubuntu) Status: New => Won't Fix ** Summary changed: - compiz crashed with SIGSEGV in pthread_mutex_lock() + [Xpress 200M] compiz crashed with SIGSEGV in pthread_mutex_lock() due to compiz loading on rez > texture size -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/745839 Title: [Xpress 200M] compiz crashed with SIGSEGV in pthread_mutex_lock() due to compiz loading on rez > texture size _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
