nvidia显卡7300LE console下Frame buffer 打开了吗？

cya1111

显卡：NVIDIA  GeForce7300LE
显卡接口：PCI-E  
显示器：19'宽屏


版本：gentoo
arch：x86_64
kernel：2.6.25-r7

现象：
X下可以实现1440x900-24@70，对kernel进行config后，uvesafb编进内核，在console下FB已经打开，可以实现1024x768-24@70，不能实现宽屏1440x900
参考安装lrmi，   keyword为x86，emerge失败（没有用源码安装方法）

grubconf内容
vedio=uvesafb:1024x768-24@70,mtrr:3,ywarp

如果设置为1440x900，doesnt work
不清楚是不是因为是PCI-E，请大家帮帮忙

“emerge失败“，emerge什么？

您的建议试试看

asmart

我在gentoo-cn groups发过一个类似的案例，希望有帮助

在内核中 如果启用了uvesafb 哪么需要将

Device Drivers ->
Graphics support ->
[]   VESA VGA graphics support
的支持关闭， 仅仅留下

<*> Userspace VESA VGA graphics support

此时 uvesafb可以正常支持自定义分辨率， vedio=uvesafb:1440x900-24@70,mtrr:3,ywarp


我22宽屏的1680x1050 控制台就这么来的

嘻嘻，能不能把你的config文件贴上来呢，我也是只保留uvseafb，谢谢
我的情况不是不支持fb，是不支持宽屏的分辨率

asmart

对啊 ，我在关闭[] VESA VGA graphics support 之前也是无法打开宽屏分辨率
vedio=uvesafb:1680x1050-24@70,mtrr:3,ywarp 无效，直接进入 fb开启但是分辨率是默认的 80x24的情况 并且最大只支持1280x1024

关闭 [] VESA VGA graphics support 之后  vedio=uvesafb:1680x1050-24@70,mtrr:3,ywarp 正常生效

不好意思，我的kernel
CONFIG_FB_UVESA=y
# CONFIG_FB_VESA is not set
我的vesa也没有设定，嘻嘻，还是不行

那就妖了哦 , 要不按照顺序重来一次? 你的v86d装了吗?

1. cd /usr/src/linux && make menuconfig;
2. Device Drivers
<*>Connector - unified userspace<->kernelspace linker ->
Graphic support ->
<*> Userspace VESA VGA graphics support
3. make;
4. emerge -av klibc;
5. emerge -av v86d;
6. make menuconfig;
7. General Setup
<*> Initial RAM filesystem and RAM disk (initramfs/initrd) support
(/usr/share/v86d/initramfs) Initramfs source file(s)
8. remake kernel & install
9. add video=uvesafb:mtrr:3,ywrap,1680x1050-24 to /boot/grub/grub.conf
10. reboot

哈哈，嘻嘻，我也是这么干的，就是分辨率设定的不一样，晚些试试，谢谢兄弟

兄弟你的结果呢，能不能把你的config贴一下，我参考下
