Linux on Clevo E4105

I'm currently running Debian Wheezy (testing) on Clevo E4105. Almost everything works out of the box. Although there was some quirks with hardware with previous kernel versions.

Kernel 2.6.39 and older missed support for wireless network card (RTL8192SE, identified by lspci as RTL8191SEvB). The driver from official site has bug in power saving code which resulted in random hangs. Cleaned version included in kernel 3.0 works well. Somewhere in 3.1, same bug was introduced. But 3.2 is ok again.

Other hardware, webcam, cardreader, ethernet NIC, dvd-rom, sound, usb controller works out of the box. I haven't tested modem or HDMI output, but some version of Ubuntu LiveCD asked me if I want to install proprietary driver for modem. And xrandr output implies that HDMI support exists.

Screen is 14" size with 1366x768 resolution (which is 112 dpi). View angles are terrible, as one can expect from TN screen, and it's a bit bluish.

Platform keys (those with Fn+something). Volume up/down/mute, play/pause, video switch, sleep button, all produce ACPI events, while touchpad disable, screen off/on, webcam on/off, wireless on/off works on lower level (I think, firmware). Unfortunately brightness can't be changed with keys as they produce no effect. Brightness itself can be changed via `xbacklight` or by writing to /sys/class/backlight/acpi_video0/brightness.


Here is lspci output:
