Acer Travelmate 634LC
For those of you buying an Acer Travelmate 634LC I've put online some info on having it run Debian GNU Linux. Not as fast as my Medion laptop but it's more power efficient and has a bigger screen (15.1" 1400x1050).
- Mobile Pentium IV 1.8GHz
- ALI Chipset
- 15.1" TFT
- 32MB videocard with TV-Out
- 512MB DDR RAM
- 30GB HDD
- 3 hour battery
- 56K modem
- 10/100Mbit Ethernet
- Acer port replicator
The longer specs, and how to get stuff working (Using Debian GNU/Linux and Kernel 2.4.19):
Audio: The normal kernel driver complains about interrupts. The ALSA driver however works great. Load snd-ali5451, snd-mixer-oss, snd-pcm-oss.
Modem: Haven't tried the modem yet, but it's supposed to be a Lucent Winmodem if you want to try.
Network: Works great with the standard 8139too driver in de 2.4.19 kernel.
Firewire: Use the OHCI kernel driver and it seems to work. I have no actual firewire equipment to test it though.
USB: (v1.1) Also use OHCI driver to get this running. Works fine.
IDE Controller: Use the ALI15xx IDE driver. Works ok. Needed hdparm to turn on 32-bit mode; DMA mode is on by default. I run:
hdparm -c 1 -u 1 /dev/hda
PCMCIA/CardBus/SmartCard: The CardBus/PCMCIA part works fine with the standard CardBus driver. The laptop also has a smartcard reader. O2 Micro however stopped their Linux support for the smartcard reader. Make sure to send them a friendly email to complain about that. They did supply me with (useless to me) binary drivers for RedHat 6.2. (Read this.)
Video: I downloaded the AGP and XFree driver from the nVidia site. They work great, including OpenGL and TV-Out. Keep in mind that the nVidia X driver is called 'nvidia' and not 'nv' like the original X driver. 1400x1050 sure is a lot more useful than 1024x768 :)
IRDA: Worked using the SIR drivers (loading irtty, ircomm-tty and ircomm). Could not get the ALI FIR driver to work.
ACPI: The ACPI in kernel 2.4.19 has problems shutting the machine down. I used a patch for 2.4.19 from http://sourceforge.net/projects/acpi. (Make sure to reconfigure the kernel.)
APM: Suppose it could work. I prefer using ACPI.
Touchpad: I used the synaptics driver from mobilix.org. Works great.
DVD/CDRW: IDE DVD-player and CD (Re)Writer. Configure kernel for SCSI emulation to use the writing features. Also put append="hdc=ide-scsi" in your lilo.conf.

It's final. February first (possibly sooner) I'll be starting at Greenpeace International.
