杀向2.6.33，外加KMS r600 3D

我终于决定从2.6.31升级到2.6.33了，可是杯具了。。

使用源里的libdrm，mesa，ati的ddx驱动，可是还是不能正常使用X

刚才切到集显（780G），安装了testing里边的kernel libdrm等，卸载了nouveau的drm，重启，正常切入radeon的KMS，启动xorg正常，glxgears有600左右。glxinfo显示DRI2已经启用，不过貌似radeon的2D显示明显不如nouveau，字体明显比独显模糊些，有些字体有些破碎，感觉NV的闭源驱动都没nouveau出色

这个……集成显卡不能这么拿来比吧……囧

你可以参考一下wiki上面的设置，xorg.conf加点内容应该还能提升性能

郁闷了。开了KMS之后X是几乎不可用的，比如打开终端，系统是直接重启

关闭KMS后还可以用用，2。6。31的时候KMS和3D加速都正常的，2。6。32的时候基本正常，只是总是不明原因的停顿，2。6。33的之后还好直接不能用了。。。

难免有错

intel 945gm一切正常,木有感到什么变化。

原来老大是R300，我R600随便测试了下，暂时没发现啥问题

貌似明显的编译问题吧……

这个可以考虑试试用aur上的mesa full，总之是去掉mesa-7.1-link-shared.patch这个补丁就行，这个问题很诡异的……我也是突然出现后来查了查……archlinux专有……

jarryson

是吗？我重新编译了libdrm-git, mesa-git(libgl-git, ati-dri-git), xorg-server, xf86-video-ati-git，还是有这个问题。

不过mesa确实是打了mesa-7.1-link-shared.patch这个补丁，还特地修改的可以打上。

弄的这两天都没用linux

hurricanek

这个我遇见过一次，查了查是这个说是这个patch的问题……而且确实解决了

这个貌似是不管重新编译多少次都没用的……就是一定要去掉……

jarryson

确实解决了。。现在没有严重错误，但是开启KMS后仍然不能运行很多程序，一运行系统直接重启。比如terminal。

完全不知道为何。在就是2。6。33里面必须关机才能成功启动系统，重启启动arch不使用KMS也出现

1. (EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM

复制代码

如果启用KMS会直接在加载radeon模块的时候重启。如此循环。必须关机或者断电后就可以。

有一次看到不断显示ACPI还是APIC error，should never happen. 因为很多时候是直接重启没有日志的

大概是

1. Spurious APIC error on CPU0, should never happen.

太杯具了这内核更新的

jarryson

仍然回到2.6.31。。。一切都很正常了。。。都不用重新编译libdrm什么的
