装完nvidia的驱动,glxgears失效了
今天刚把nvidia驱动装上,可是glxgears不能用了,显示如下:Xlib:extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual
这是怎么回事啊?? :shock: ,确定/etc/X11/XF86Config没问题吗?(有XF86Config-4的话会优先使用这个)
具体我也说不上来,不过我安装完了以后去掉了GLcore就正常了。 我的XF86Config-4有个这个
Section "Device"
Identifier "NVIDIA GeForce 2 MX (generic)"
Driver "nv"
BoardName "Unknown"
EndSection
Section "Device"
Identifier "Linux Frame Buffer"
Driver "fbdev"
BoardName "Unknown"
EndSection
Section "Screen"
Identifier "Screen0"
Device "NVIDIA GeForce 2 MX (generic)"
Monitor "PAT 778FT"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1024x768"
EndSubSection
EndSection
其中Section "Device"为什么有两个,需要改什么吗?
呵呵,搞定了
偶把这个Section "Device"
Identifier "Linux Frame Buffer"
Driver "fbdev"
BoardName "Unknown"
EndSectio
删掉
把
Section "Device"
Identifier "NVIDIA GeForce 2 MX (generic)"
Driver "nv"
BoardName "Unknown"
EndSection
的 Driver "nv"改成 Driver "nvidia",从起X,居然搞定了~呵呵
glxgears 结果
2887 frames in 5.0 seconds = 577.400 FPS
3794 frames in 5.0 seconds = 758.800 FPS
3793 frames in 5.0 seconds = 758.600 FPS
3793 frames in 5.0 seconds = 758.600 FPS
3776 frames in 5.0 seconds = 755.200 FPS
3469 frames in 5.0 seconds = 693.800 FPS
3861 frames in 5.0 seconds = 772.200 FPS
3860 frames in 5.0 seconds = 772.000 FPS
KDE的启动速度疯了,也能看OpenGL的那个"陶醉"的屏保了~呵呵,不错哦 。。。。。。
恭喜,呵呵。
你安装了nvidia驱动就不需要framebuffer了,删掉才对,唔唔,另外,我曾经手动编辑过这个文件。
Section "Device"
Identifier "NVIDIA GeForce 2 MX (generic)"
Section "Screen"
Identifier "Screen0"
Device "NVIDIA GeForce 2 MX (generic)"
这两个地方,上一个的Identifier一定要和下一个的Device相符,呵呵,因为认不出我的6600,我手动修改过以后没法启动X才发现的, :oops: 我的也有问题,版主解决下阿!!!
# glxgears
glxgears: Error: couldn't get an RGB, Double-buffered visual. 仔细检查一下你的/etc/X11/XF86Config
或者Xorg那个 15位色深下glxgears不能运行。
