[edit] Hibernation / Suspend-to-RAM
Suspend to RAM works with the following:
- s2ram utility (part of the openSuSE suspend package)
- vanilla 2.6.25
- supplied kernel dot configuration file #2.6.25.
- supplied /etc/acpi/events/power script (found below)
- supplied /etc/acpi/lid.sh script (found below)
- supplied /etc/conf.d/powersave script in the Gentoo-specific section
[edit] S2RAM Installation
First emerge the latest s2ram:
echo sys-power/suspend >> /etc/portage/package.keywords emerge -u suspend

[edit] Xorg
As of 8 March 2008, the stable radeon driver (xf86-video-ati 6.6.3) issues an interrupt for each vertical screen refresh, which prevents the CPU from entering lower sleep states resulting in wasted power usage. This can be fixed by unmasking and emerging the unstable (xf86-video-xati 6.8) driver, in addition to using the latest xorg-server version (xorg-server 1.4.0.90-r3)
| File: /etc/portage/package.keywords |

| File: /etc/portage/package.unmask |
x11-drivers/xf86-video-ati |
[edit] startx
The latest 6.8 radeon driver doesn't properly calculate the DPI (even with the DisplaySize attribute in xorg.conf) which results in KDE or GNOME using massive fonts. The temporary fix until the driver is fixed is to explicity tell X the DPI.
Edit /usr/bin/startx and add the dpi argument as following:
defaultserverargs="-nolisten tcp -br -dpi 100"
[edit] Portions of Xorg Configuration
It took me a while to figure out why X was feeling so slow (along with CPU spikes to 100%) when using simply GUI elements in 2D, even with DRI enabled. Clicking the file menu in Firefox would spike the CPU to 100% for a split second.
Enabling the XAA software renderer and other small tweaks significantly improve 2D performance in xorg (tested with gtkperf).

It is important that the NSC PC87108/PC87338 driver is compiled as a module (will be called nsc-ircc). You may want to enable additional protocols which your IrDA devices support.
[edit] Related packages to install
sys-apps/setserial net-wireless/irda-utils
[edit] Configuration
Unfortunately, the 8250 serial driver will grab the IrDA port on boot. So we need to release it before loading the nsc-ircc module.
| File: /etc/serial.conf |
/dev/ttyS1 uart none |
| File: /etc/modules.autoload.d/kernel-2.6 |
nsc-ircc |
| File: /etc/conf.d/irda |
IRDA=yes IRDADEV=irda0 DISCOVERY=yes |
Finally, make sure that everything starts in the correct order on boot:
rc-update add serial boot rc-update add irda default
This will make the /etc/init.d/serial start before the nsc-ircc module is loaded, and /etc/init.d/irda afterwards. Test your IrDA port by bringing an IrDA device near the port and running
irdadump
Note that users who want to access the IrDA port need to be in the uucp group.

The following settings are applied during startup and after resuming from hibernation. This script is called from /etc/conf.d/local.start and /etc/acpi/events/lid (on resume).

[edit] System Maintenance
[edit] Firmware Upgrade from DELL
Upgrading the firmware is straight forward with freedos, mtools, and syslinux:
emerge -u mtools syslinux echo 'drive a: file="/boot/freedos.img"' > /etc/mtools/mtools.conf echo 'mtools_lower_case=1' >> /etc/mtools/mtools.conf mount /boot cp /usr/lib/syslinux/memdisk /boot wget http://www.fdos.org/bootdisks/autogen/FDSTD.288.gz -O - | gunzip > /boot/freedos.img cd /tmp wget ftp://ftp.work.acer-euro.com/notebook/travelmate_4400/bios/bios%201.20.zip unzip bios\ 1.20.zip cd Bios\ 1.20 unzip FBB033WW.zip rm FBB033WW.zip */*.EXE mdeltree a:/bios mmd a:/bios mcopy -bsv * a:/bios
Now add the following to your /boot/grub/grub.conf, reboot into FreeDOS, and run cd bios, BOL120.bat:
title FreeDOS [Acer BIOS update] kernel /memdisk initrd /freedos.img
The latest BIOS can be found at Acer's support site and the latest FDSTD.288.gz boot disk at fdos.
