Setting Hidpi

I did not set the DPI in Xorg. I just change in KDE the font DPI to 166 pp. This setting works fine for almost everything inside KDE but the xterm is not affected and the font looks tiny. In Window Maker everything looks small as well, but I don't know if it is possible to change that.

Another point to improve is the font size in the tty consoles, now it is very small. I know how to do it but I still have to.

Just to remember, the screen resolution is 3200 x 1800 @ 276 ppi.

Keyboard layout

My current laptop uses a German keyboard (QWERTZ), also I use to use another US-international, so I have to configure the system to use both.

I need to write in Spanish frequently. The default German layout (no death keys) works fine but it doesn't allow to write the ñ letter. The legacy version uses death keys and allows to write the lovely ñ.

Linux console:
To change the default keyboard layout, create the file:
# /etc/rc.d/rc.keymap

#!/bin/sh
# Load the keyboard map.  More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
 /usr/bin/loadkeys de-latin1.map
fi

Xorg
This settings will affect all the Xorg application, thats include KDE and Window Maker. Just create the following config file.

# /etc/X11/xorg.conf.d/90-keyboard-layout.conf

Section "InputClass"
Identifier "keyboard-all"
MatchIsKeyboard "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "XkbLayout" "de"
Option "XkbVariant" "legacy"
Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

KDE
Normaly KDE will use the keymap defined by Xorg, but in the case you want to set it again in KDE, just choose the German variant German (legacy) as keyboard layout in the Input devices section of the System Settings.

There still a problem prowling around. It is the special keys, most of them works ok with the exception of the airplane mode and the increase and decrease brightness. They doesn't work, I think they are not visible in linux, but I have to check this.

Also I have to try what happens with the second keyboard, I have not tried yet.

Synaptics touchpad configuration in Xorg

I wanted to customize the configuration of the Synaptics' driver because the click buttons were swapped and I wanted to disable it while typing.

This is the Xorg configuration file I wrote:

# /etc/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"

Identifier "touchpad"

Driver "synaptics"

MatchDevicePath "/dev/input/event*"

MatchIsTouchpad "on"

 Option "TapButton1" "1"

 Option "TapButton2" "3"

 Option "TapButton3" "2"

 Option "VertEdgeScroll" "on"

 Option "VertTwoFingerScroll" "on"

 Option "HorizEdgeScroll" "on"

 Option "HorizTwoFingerScroll" "on"

 Option "EmulateTwoFingerMinZ" "40"

 Option "EmulateTwoFingerMinW" "8"

 Option "PalmDetect" "1"

 Option "PalmMinWidth" "10"

 Option "PalmMinZ" "100"

EndSection

The touchpad is not really disabled while typing. Instead, it is sensitive to recognize the palm when I touch it accidentally, avoiding to do a click.

Slackware 13.1+ i810

I have installed Slackware 13.1 six month ago and since that I have a problem with video. Sometimes while I'm working the screen keeps freezing, I can move the mouse and see how the pointer moves, but always the screen shows the same image. In the console I have found the following error:

(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Input/output error.

I have tried a pair of times solve the problem, but never successfully. Now I'm going again, taking care of documenting everything.

My graphic card is: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

I used to use the i810 driver from Intel, but now this driver is deprecated and replaced by Intel graphic driver that support more cards from Intel.

The configuration:

• Kernel: 2.6.33.4-smp
• Xorg server: 1.7.7
• xf86-video-intel: 2.11.0

I have found these error in Xorg.0.log :

(II) LoadModule: "fbdev"
(WW) Warning, couldn't open module fbdev
(II) UnloadModule: "fbdev"
(EE) Failed to load module "fbdev" (module does not exist, 0)

I have used xorgsetup to create a xorg.conf file, after that I have not seen the error again. But glxgears goes very slow yet, and possibly the video will fail again.
