Linux 99% working, 1% really nasty bug - a little story

I got two Eee Top units in the office about a week ago to play with. The shipped Windows XP works fine, but I don't need it. I need Linux, so I tried it on... bummer, I end up with a black screen.

I turned the settings up side down, still no luck. By the looks of it, the back light is turned off when the "intel" video driver intializes, so I switched to "vesa". This worked fine. I had a picture. I then configured the touch screen and it worked perfectly. I even network booted the thing without much hassle.

Who should I hate now? Intel? Asus? Both? All that's required to get it moving is a picture with the "intel" driver sad

And there's no Express Gate anywhere in sight to take a glimpse at and figure out how it does its magic.

I even sent a message to the xorg list, but it passed unnoticed.

So, long story short:

- Touchscreen: works
- Display: intel driver turns the backlight off, and the backlight software controls are broken; vesa driver works
- Everything else: works
- Distros tried: Ubuntu 8.10, Ubuntu 7.10, Eeebuntu

I tried hacking the drivers to fix the backlight issue, but I ran out of ideas of where to look. If anyone brighter than me wants to give it a shot, I can let you into one of these machines.

How have you got on.

I got puppy linux working with the screen and that, but wireless would not work.

I have tried Knoppix, Ubuntu and the video just does not come on, even with VESA.

The problem is related possibly to a bug with the integrated graphics card according to ubuntu forums.

I haven't tried the wireless, as that's not my main concern. As for the "vesa" driver, I just substituted the "intel" driver with it and it worked. You can see my (really detailed) xorg.conf following the link in the first post. Here it is again: http://wiki.linuxmce.org/index.php/Asus_EeeTop

I used Ubuntu 7.10 and 8.10 btw.

I'm running Gentoo on my ET1602, and I'm experiencing the same issue using the intel X11 driver. VESA works great after I set a fixed modeline (Modeline "1366x768@75" 111.93 1366 1392 1816 1848 768 782 792 807) within the Monitor section. Without it, VESA would silently drop to 800x600 which is really horrible on the Eee Top's screen.

I also managed to get WiFi working using the drivers provided by Ralink themselves.
Download http://www.ralinktech.com.tw/data/drive … 0.tar.bz2, unpack it, edit os/linux/config.mk to support wpa_supplicant and also native support for network manager (HAS_WPA_SUPPLICANT=y, HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y), even if you don't use network manager. Then `make` and `make install` the driver. You can then load it (`modprobe rt2860sta`). It'll provide a wireless device called ra0. wpa_supplicant can be used with the wext driver (-Dwext). For more info, read the README_STA within the source directory of the RaLink driver.
