linux下如何修改硬件中断了?????

zyl19861126

我装了 ati 的 fglrx 驱动,  但是启动的x的时候 总说 XIO: 致命的错误 等消息, 但是还是可以启动进去..

我再 /proc/interrupt那里看了, 显示 sata_nv ohci_hcd:usb1 fglrx共享10号中断, 难道是 3 个共享10中断发生错误, 所以, 问下有没有办法 更改中断了?

zyl19861126

freebsd可以再内核配置里面改, 不知道linux可以没有

kenlen

...................

dmesg | grep fglrx
dmesg | grep agp
lsmod
glxinfo
先确认自己fglrx有没有装好..

kenlen

致命错误在X上面有很多情况会出现
最好把starx 的信息
特别是 EE那些错误贴出来看看

fglrx应该是没有正确加载
fglrx: No matching Device section for instance (BusID PCI:7:0:1) found
可能是字体服务出错了
重新配置X
和IO中断请求时两码事情。
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0"

fglrx确实是加载了， 但是他开始的时候显示没有 匹配设备， 后面我进X后 看见 加载了， 并且我可以玩3D游戏， 说明加载了。 lsmod 也显示加载了。

字体不会出错， 因为都没有提字体， 它报错。
搞不明白的就是， 为什么 我登录进X的时候没有报XIO： fatal, 但是我一登录出来的时候就报错了？？？？

kenlen

登陆XIO没有报错
但是退出报错
很有可能是字体问题

最好运行这个命令看看xerror具体信息
startx 2>&1 | tee xerror.log

fglrx: No matching Device section for instance (BusID PCI:7:0:1) found
X重新配置一遍下看看
我觉得应该是fglrx没有安装正确才会出现的
