我在用Fedora 22并且遇到了问题Nvidia GeForce GTX765M驱动程序。我无法调整笔记本电脑屏幕亮度,也无法从 hdmi 输出视频。我在这里和 Fedora 论坛上做了一些研究,以下是一些可能有助于诊断问题的要点:
Nouveau 驱动程序已安装
sudo dnf install *nouveau*
给出结果:
Package xorg-x11-drv-nouveau-1:1.0.11-2.fc22.x86_64 is already installed, skipping. Dependencies resolved. Nothing to do. Complete!
xorg.conf 没有与背光或 nvidia 相关的条目:
ls /etc/X11/xorg.conf.d
给出结果:
00-keyboard.conf 50-synaptics.conf
这显然与键盘和触摸板有关。
/sys/class/backlight 目录是空的。
lspci 相关结果有:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) ... 01:00.0 3D controller: NVIDIA Corporation GK106M [GeForce GTX 765M] (rev a1)
Nvidia 驱动程序被抑制(虽然我也尝试注释该行并且重新启动,但是没有用):
cat /usr/lib/modprobe.d/dist-blacklist.conf
给出:
... # framebuffer drivers blacklist aty128fb blacklist atyfb blacklist radeonfb blacklist i810fb blacklist cirrusfb blacklist intelfb blacklist kyrofb blacklist i2c-matroxfb blacklist hgafb blacklist nvidiafb #HERE IT IS! blacklist rivafb blacklist savagefb blacklist sstfb blacklist neofb blacklist tridentfb blacklist tdfxfb blacklist virgefb blacklist vga16fb blacklist viafb ...
还有其他建议吗?我合并了两个问题(背光和 HDMI),假设它们都源于同一个问题,但我可能弄错了。提前致谢。
