Hi everyone. I'm trying to run X on my Overo Air using the latest pre-built desktop image. Now I'm brand new to running X when it doesn't start automagically so please forgive me if I'm asking the obvious. Here is the result of my try: overo login: root root@overo:~# X Fatal server error: Could not create lock file in /tmp/.tX0-lock Please consult the The X.Org Foundation support at http://wiki.x.org for help. I looked back at the output and see segmentation faults along the way that look suspicious, though they may or may not be related here I thought them worth mentioning: Remounting root file system...

Hi, It's usual in the Linux desktop world for X to be started via a script called 'startx'. On my desktop that is in /usr/bin. I bet you will have more luck using that, if you have it (though there may be other issues specific to Gumstix that I don't know about).

I'll try that. As far as the segmentation faults go I think I figured that out. I am running Ubuntu in VMWare and if I do not carefully umount the volume AND disconnect from VMWare AND eject from Windows 7 then nothing works. It seems that it is important to umount all partitions of the device (/dev/sdb1 and /dev/sdb2) before disconnecting from VMWare. This might be obvious but maybe not. The symptoms I saw when I did not umount both partitions is that I get a kernel panic on boot. After jumping through all of those hoops I am able to boot and see the X test running (at least that's what I think is happening.)

Well, that didn't work. It must be that my expectations are not correct. When I create a MicroSD card to boot from using the the pre-build MLO, uImage, u-boot and the filesystem from the omap3-desktop.tar.bz what should I expect?

Hi, Trying to chase down some anomalous code behavior, I just now went through an exercise to enable the following kernel config items :- CONFIG_KERNEL_DEBUG=y CONFIG_DEBUG_SLAB=y CONFIG_DEBUG_SLAB_LEAK=y CONFIG_DEBUG_PAGEALLOC=y CONFIG_DEBUG_SPINLOCK=y CONFIG_DEBUG_SPINLOCK_SLEEP=y CONFIG_DEBUG_STACK_USAGE=y CONFIG_KALLSSYMS_ALL=y CONFIG_DEBUG_DRIVER=y CONFIG_DEBUG_VM=y When the new build booted up, I was flooded with thousands of debug messages during the reboot. I've sorted and uniq'd them, and these are what I was seeing, mostly oft-repeated :- slab error in cache_alloc_debugcheck_after(): cache `bdev_cache': double free, or memory outside object was

overwritten slab error in slab_destroy_debugcheck(): cache `UNIX': start of a freed object was overwritten My kernel is linux-omap3-2.6.30-r46, and the build probably dates from early October 2009. I have done nothing to the tree itself, I've merely added two kernel module builds. I'm building on FC11, which some have dissed, but I've been with FC since FC3 and I do not believe that FC implies any less of a good build than any other distro. Is this sort of thing to be expected? I.e. are the messages spurious, or do they relate to real errors in the execution? If the latter, I wonder whether any Q.A. at all was done on the build by Gumstix, before it was released. Cheers, Mike Turner |
