哎，好郁闷啊，显卡驱动被我折腾坏了，还是没弄好，只好来求救啦！
升级到 13.1 后，我把原来源 ftp://download.nvidia.com/opensuse/12.3/ 里针对 12.3 的驱动卸载了之后，想尝试下 nouveau 驱动 。
重启后，能进入桌面，但是分辨率没法调节，于是我又下载 nvidia 的官方驱动，进入 level 3 安装后，重启进入桌面，可是估计不到一分钟整个桌面就 hang 住了，于是我怀疑这个驱动有问题，重启后进入 level 3 卸载掉驱动，删除 /etc/X11/xorg* 后想再次尝试 nouveau 驱动。
可是，就从下开始就再也没见到过 KDM 的登录界面，现在只能进入 console 了。之后反复尝试过手动安装 Nvidia 官方驱动都是一样的效果了。
我实在不知道怎么回事了。
现在切到 Ctrl+Alt+F7 就是一张小蜥蜴的图片，按 ESC 后，显示的最后几行如下：
OK ] Started LSB: Samba SMB/CIFS file and print server.
Starting CUPS Printing Service ..
OK ] Started CUPS Printing Service.
我的显卡是
02:00.0 VGA compatible controller: NVIDIA Corporation C77 [GeForce 9100M G] (rev a2)
现在系统里是手动装的 Nvidia 驱动，从系统日志里看，启动时有以下信息：

我刚刚把 Nvidia 的闭源驱动卸载了，添加了 XOrg 的源，更新了 nouveau 的驱动，终于可以进桌面了，但是分辨率是 640 x 480 ，桌面调节分辨率？
Ok, 了，去掉 nomodeset 分辨率就对了，但是 consloe 似乎还看到 “FATAL: module nvidia not found” 的信息，不明白，为什么 内核还要去找 nvidia 的模块呢？
不是内核是 Xorg 找的，它发现你是 N 卡，找驱动的顺序就是 nvidia → nouveau → nv → vesa。看那个没用，你得看你最终哪个 success 了。
