Current Issues

See Notes section below for issues that were resolved in some way. This section contains issues that have so far not been resolved, and that needed some explanation.

Hotkeys

Display-related hotkeys do not work (brightness, monitor blank, switch monitors). See [https://bugs.launchpad.net/ubuntu/+source/hotkey-setup/+bug/128572]. Do not press these keys!

Card Reader

I put a MMC card into the internal card reader (see system info below). It doesn't automount or appear in dmesg.

I looked at the MUSCLE site ([http://www.linuxnet.com/sourcedrivers.html]) for a driver, but the reader on this laptop does not have a driver there.

Someone [http://megawiki.org/wiki/DimitriS420] has a laptop with the same card reader working with the SDHCI driver. The kernel I am using does not have SDHCI in it (see Notes below). Later, we compiled a new kernel with the SDHCI driver and tried to load it, but on this computer, loading the SDHCI module causes the system to hang (enough so that a hard reboot is all you can do to restart it).

A generic USB external card reader that I plugged in worked just fine with an MMC card, by the way.

Modem

The modem (Motorola SM56) on this system is not working. After installing the sl-modem-daemon package (compiled from source with the ASLA sound drivers), various pieces of software say they can see the modem, but it's not actually dialing out.

Hardware details

Notes

This section lists notes of issues that were resolved.

Install

The Ubuntu 7.04 Feisty Faun installer ISO disk downloaded on July 23 2007 (using kernel 2.6.20-15-generic) does not work out of the box. This Everex machine has the same issue as the Averatec and other laptops mentioned on this page: [http://www.fitzenreiter.de/averatec/index-e.htm], which is that the installer CD does not boot. It hangs in the hardware detection phase.

I tried a bunch of different boot options mentioned on various Ubuntu forums, and also a bunch of different distros (Fedora, Mandriva, Knoppix, Simply Mepis), and none of them worked.

The installer download available on the site above ("doesn't contain the SDHCI module and a 8139too module compiled for PIO only access") allowed Ubuntu to install normally.

We later compiled the 2.6.22 and 2.6.23 RC1 kernels (using the kernel source from kernel.org), and verified that an 8139too module compiled with the default MMIO access allowed causes the boot process to hang, and loading the SDHCI module also causes the boot process to hang.

Screen Resolution

After installation, the maximum screen resolution shown in System / Preferences / Screen Resolution is 1024x768. The native resolution is 1280x800. Installation of 915resolution and a reboot fixed this issue. Command:  apt-get install 915resolution . Another alternative was upgrading from the i810 X-Windows video driver to the intel video driver ( apt-get install xserver-xorg-video-intel), which gives better support for changing resolutions.

I have an external monitor. Using the i810/915resolution system, I was able to set up an extended desktop using both monitors, via Xinerama. But apparently the intel driver doesn't support Xinerama, and I'd need to get the development version of xRandR to have an extended desktop. I haven't tried that yet.

Mirroring the display was kind of a problem too. My external monitor has a 4x3 aspect ratio, while the laptop display has a 16x9 (wide-screen) aspect ratio. The i810 driver lost the left side of the screen on the external monitor; the intel driver lost the bottom of the screen on the built-in monitor. The latter would be preferable for purposes of a projector, since at least then the view of the audience would be correct. I'm not sure what the "correct" behavior would be -- perhaps distortion but a complete view on both? It would be good to have the option, but neither driver appears to allow that, as both cause X to give resolution options only at the aspect ratio it thinks would be useful.

Wireless

Wireless did not work out of the box on this laptop, which has a Ralink RT73-based USB wireless card, on an internal USB bus (i.e. the card is not removable). The symptom was that the Network Manager could sometimes scan and detect local access points, but it would not connect to them (it would time out eventually; message on screen was "Waiting for Network Key"; dmesg reports timeout). This happened with both open access and WEP.

I tried several remedies from several sites, and finally got things to work as follows:

• Blacklist or remove existing wireless card drivers, such as the rt73usb module.

• Download the driver source from Ralink ([http://www.ralink.com.tw/Home/Support/Linux.html]). Make sure to get the latest USB version for the RT73 chip.

• Extract all the files, cd to the Modules directly. chmod 755 and fromdos all the files.
• Follow the instructions in the README file to build, install, and configure the driver. This involves creating a configuration file called /etc/Wireless/RT73STA/rt73sta.dat.
• Remove the Network Manager application. It does not work well with this driver.

• Use to bring up the wireless network.

CD/DVD Drive

This computer has an internal CD/DVD RW drive. The CD portion worked initially without any trouble. Playing DVD movies also works fine, after following the instructions on [https://help.ubuntu.com/community/RestrictedFormats], using the Xine player. Burning a CD also works fine, out of the box.

Touchpad

Initially, the scrolling behavior marked on the side of the touchpad did not work. However, a bit of tweaking on the xorg.conf file (turning on the "SHMConfig" option to the Synaptics Touchpad input device section) made it work. The "qsynaptics" application also allowed me to make the touch pad not respond to taps, which were happening a lot by mistake while I was typing.
