gentoo下装ati驱动的问题

在root下一切正常，在用户下3d没有加速。在用户下运行fgl_glxgears命令：出现以下内容
fglX11AllocateManagedSurface: __FGLTexMgrCreateObject failed!!
FGLTexMgr: open of shared memory object failed (Permission denied)
__FGLTexMgrCreateObject: __FGLTexMgrSHMmalloc failed!!!

这是什么意思啊

问题已解决，在fstab里增加：tmpfs /dev/shm tmpfs defaults 0 0
还是不明白什么意思，希望高手指点，谢谢。

楼主第二帖里的是什么文字？那美克星语？

简单的说，如果应用程序使用了posix shared memory（注意是posix不是SysV)，就要加上这一行

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:

none /dev/shm tmpfs defaults 0 0

有个问题很弱智的，但困扰我很久了，还是问一下吧。
那就是装ATI驱动后的fglrx模块开机时加载，升级ATI驱动时非要把它卸载后才正常，可我从modules.autoload.d/kernel_2.6里去掉了fglrx，它还是加载，大虾给指点一下吧，如何让它在启动时不加载。:thank

/etc/hotplug/blacklist
加入这个文件

/etc/hotplug/blacklist
加入这个文件
====================
行是行，还是麻烦。我觉得最好的是，在内核里把unload modules选上，然后进xwindow时选控制台安全模式会话，在该模式下运行/etc/init.d/xdm stop，然后rmmod fglrx。

zhllg · 发表于 2006-4-7 12:19:57

您不是认真的吧
加入blacklist需要且之需要一个命令
echo fglrx >> /etc/hotplug/blacklist
哪个麻烦，正常人都看的出来的吧

baryon · 发表于 2006-4-7 12:29:20

但这招还得配合在在kernel－2.6中注释掉agpgart等其它模块才奏效，而且注释掉后，等会儿还要放出来，是麻烦一点点。呵呵。
