Revision as of 01:45, 14 June 2008
This guide is based on Slackware 12.1 upgraded to kernel 2.6.25.5. Mostly random notes, hopefully will be shaping up soon.
Contents
Specs
- Model 7658CTO
- T9300 CPU
- 14.1" (WXGA+, 1440x900) screen
- Intel Graphics Media Accelerator X3100
- Intel PRO/Wireless 4965AGN Mini-PCI Express Adapter
- UltraBay Slim Super Multi-Burner Drive
Installation
- Create a set of Rescue and Recovery discs before proceeding, it'll save your bacon when/if (probably when) things go bad.
- Used a Ubuntu boot CD (8.04) and Gparted to split off a new Linux partition from the main Windows partition. This is probably possible with fdisk/cfdisk but Gparted graphical, simple, and straightforward. Leave the rescue partition (~8 GB) alone, newer (early-2008?) T61s ship with Rescue and Recovery version 4 which vastly improves the boot options.
- Insert and boot from the Slackware 12.1 DVD, no key presses are necessary as the drive is set as the first boot device from the factory.
- Start cfdisk and verify that that:
- The Linux partition is flagged as bootable
- The NTFS partition is not bootable
- Create a Linux swap partition. There's a limit of four primary partitions which works out fine (NTFS, Linux, Linux swap, Rescue).
- Run setup
- Disk space shouldn't be a problem, choose the full option
- Install LILO to the Linux partition. This leaves the MBR untouched and retains the ability to boot into the rescue partition.
Sound (or lack of it)
The speaker is not activated at boot. Edit the /etc/asound.state file and change false to true:
name 'Speaker Playback Switch' value.0 false value.1 false
Run alsactl store after saving to preserve the changes through restarts.
Temporary fixes are running amixer sset Speaker toggle or activating the speaker through Kmix's Switches tab.
Console Resolution
At least for the T61, the Wikipedia VESA BIOS Extensions page lists incorrect modes. vbetest (requires lrmi) outputs:
[352] 768x480 (256 color palette) [353] 768x480 (5:6:5) [354] 768x480 (8:8:8) [355] 960x600 (256 color palette) [356] 960x600 (5:6:5) [357] 960x600 (8:8:8) [358] 1280x800 (256 color palette) [359] 1280x800 (5:6:5) [360] 1280x800 (8:8:8) [361] 1440x900 (256 color palette) [362] 1440x900 (5:6:5) [363] 1440x900 (8:8:8) [261] 1024x768 (256 color palette) [279] 1024x768 (5:6:5) [280] 1024x768 (8:8:8) [274] 640x480 (8:8:8) [276] 800x600 (5:6:5) [277] 800x600 (8:8:8) [257] 640x480 (256 color palette) [259] 800x600 (256 color palette) [273] 640x480 (5:6:5)
Adding 512 to the bracketed number gives the correct Linux video mode:
640×480 | 768x480 | 800×600 | 960×600 | 1024×768 | 1280×800 | 1440×900 | |
---|---|---|---|---|---|---|---|
256 color palette | 769 | 864 | 771 | 867 | 773 | 870 | 873 |
16-bit (5:6:5) | 785 | 865 | 788 | 868 | 791 | 871 | 874 |
32-bit (8:8:8) | 786 | 866 | 789 | 869 | 792 | 872 | 875* |
Replace the existing vga=XXX with one of the above numbers in /etc/lilo.conf then re-run lilo.
*Doesn't work, screen is distorted and unusable. Other 32-bit resolutions are ok.
To verify the setting run dmesg | grep vesafb:
vesafb: framebuffer at 0xe0000000, mapped to 0xf8880000, using 5062k, total 7616k vesafb: mode is 1440x900x16, linelength=2880, pages=1 vesafb: scrolling: redraw vesafb: Truecolor: size=0:5:6:5, shift=0:11:5:0
X Resolution
Given the size (14.1") and resolution (1440x900) the correct dpi is 120.4.
xdpyinfo | grep dots should display resolution: 121x120 dots per inch. Visit Cherife Li's guide for a xorg.conf with the correct screen and device sections.
Advanced Trackpad
The default settings don't utilize the trackpad's advanced functions (vertical/horizontal scrolling, etc) in X.
Comment out the options line in /etc/modprobe.d/psmouse/ to recognize the trackpad as a SynPS/2 Synaptics TouchPad instead of a PS/2 Synaptics TouchPad in /proc/bus/input/devices.
The Synaptics TouchPad driver is available as a SlackBuild.
The InputDevices section of xorg.conf:
# ********************************************************************** # Input devices # ********************************************************************** # ********************************************************************** # Core keyboard's InputDevice section # ********************************************************************** Section "InputDevice" Identifier "Keyboard0" Driver "kbd" EndSection # ********************************************************************** # Core Pointer's InputDevice section # ********************************************************************** Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizEdgeScroll" "0" Option "LeftEdge" "1700" Option "RightEdge" "5300" Option "TopEdge" "1700" Option "BottomEdge" "4200" Option "FingerLow" "25" Option "FingerHigh" "30" Option "MaxTapTime" "180" Option "MaxTapMove" "220" Option "VertScrollDelta" "100" Option "HorizScrollDelta" "100" Option "MinSpeed" "0.09" Option "MaxSpeed" "0.18" Option "AccelFactor" "0.0015" Option "SHMConfig" "on" Option "TapButton1" "1" Option "TapButton2" "2" Option "TapButton3" "3" EndSection Section "InputDevice" Identifier "UltraNav Trackpoint" Driver "mouse" Option "CorePointer1" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" Option "Emulate3Buttons" "on" Option "Emulate3Timeout" "50" Option "EmulateWheel" "on" Option "EmulateWheelTimeOut" "200" Option "EmulateWheelButton" "2" Option "YAxisMapping" "4 5" Option "XAxisMapping" "6 7" Option "ZAxisMapping" "4 5" EndSection
Problems/Issues
- Running AC-only will restrict the CPU speed to 800Mhz or 1.2Ghz. See Problem_with_CPU_frequency_scaling for more details, the fix (until a post-2.6.25 kernel adds a patch) is adding append=processor.ignore_pcc=1 to lilo.conf.
- Suspend-to-RAM from console - Won't restore, screen remains blank. Problems_with_ACPI_suspend-to-ram lists all sorts of woes.
Boot Hot Keys
- F1 = BIOS
- F11 = Boot recovery partition
- F12 = Select boot device
