Xfce4 Power Manager, NVIDIA, Nouveau backlight issue
Recently I move back to use my (around) 4 years old laptop, HP Pavilion dv3. It has NVIDIA graphic card. But since I (re-)installed Arch Linux 64 bit on it, I failed to run the X11 with the proprietary NVIDIA driver. As a result, I used the Nouveau module instead. Then, I tried several times and finally successfully run the X11 with NVIDIA driver.
To use the Nouveau module, in the mkinitcpio.conf, we have to add in “nouveau” module, then build the initramfs (refer to wiki page). And use the “Xorg -configure” to generate the xorg.conf.
Arch Linux Ristretto show thumbnail freeze problem
After I tried to enable show thumbnail in ristretto (image viewer), the application freeze. Whatever image I open with ristretto, all will freeze. To solve this, remove ~/.config/xfce4/xfconf/xfce-perchannel-xml/ristretto.xml, logout, and login. The application will not freeze anymore. But I don’t try to enable the thumbnail after this.
