General

Users have reported that running a second x server can give a more responsive quake LINK
Excerpt/Conclusion from the above link:

  • To run your engine in a second X server (which might help on various occasions) on virtual terminal 12 (you could switch between regular X and 2nd one by pressing ctl+alt+f7 and ctr+alt+f12):

xinit /path/to/your/executable_or_script -- :1 vt12

  • If you want you can also create a new xorg.conf for this new X server and specify it via attaching "-config xorg_qw.conf" in the command line.

xinit /path/to/your/executable_or_script -- :1 -config xorg_qw.conf

  • You can also simply type xinit -- :1 to get an console where you then start the game.

Mouse

  • Guide to change mouse Hz: LINK
  • Run mouse handling in its own thread in ezQuake with: in_mmt 1


EVDEV mouse
To get EVDEV mouse working you will have to make /dev/input/device readable, since we now dont know which device is our mouse, we just do "chmod +r -R /dev/input/" which must be run as root.
In ezQuake there is a command to check what event the mouse is on, check by typing: in_evdevlist
Set in_mouse 3 and then in_evdevice /dev/input/eventX where X is the number you got from in_evdevlist.
Type in_restart and it should work!

Note: If you get laggy/skippy input from the keyboard when using high refresh rate mouse polling, you could try switching keyboard drivers if you want to keep the mouse the way it is. My keyboard frequently ignored my commands when using 1000hz evdev+ evdev keyboard, so I switched them to mouse/kbd X11 drivers and things seem okay now.

Screen

Sound

ezQuake 2.1 has new soundcode:
ezQuake 2.1 has new soundcode for ALSA/OSS/Pulseaudio ported from FodQuake. This will allow you to have other sound sources than only ezQuake.

  • Choose sound driver with s_driver alsa/oss/pulse
  • If you are running on a system without pulseaudio and got problems with new ALSA code, you can first try setting s_alsa_noworkaround 1 and do s_restart.
  • If that doesn't help, you can switch to the old drivers (called legacy) with cl_uselegacydrivers 1 for ALSA/OSS (still chosen by s_driver).


Information below is for the old soundcode ONLY:

  • Got software mixing and problems with sound in ezquake? SOLUTION: add +set s_device dmix to command line and don't use local .asoundrc
  • if you don't get sound at all with those settings try doing these things:

- add yourself to group 'audio' ($ addgroup username audio) ; then disconnect/reconnect (login)
- $ echo 'ezquake-gl.glx 0 0 direct' > /proc/asound/card0/pcm0p/oss (might need to chmod it first)

Launch ezQuake by clicking on qw:// links in your browser

KDE (untested):

[Protocol]
exec=/path/to/qw/ezquake-gl.glx +qwurl '%u'
protocol=qw
input=none
output=none
helper=true
listing=false
reading=false
writing=false
makedir=false
deleting=false
icon=package
Description=qw
  • Save this code in ${KDEHOME}/share/services/qw.protocol

Gnome (untested):

gconftool-2 -t string -s /desktop/gnome/url-handlers/qw/command exec /path/to/qw/ezquake-gl.glx +qwurl "%s"
gconftool-2 -t bool -s /desktop/gnome/url-handlers/qw/enabled true
gconftool-2 -t bool -s /desktop/gnome/url-handlers/qw/needs_terminal false

Adapted from http://ubuntuforums.org/showpost.php?&p=2618481

Firefox:

Create a new file containing this: 

#!/bin/sh
#
# ezquake launcher script for qw:// links
#
exec /path/to/qw/ezquake-gl.glx +qwurl "$@"
  • Save it as qwconnect.sh and chmod +x it. Place it in your qw folder.
  • In Firefox go to about:config.
  • Rightclick, "new" -> "string": "network.protocol-handler.app.qw" "/path/to/qwconnect.sh"
  • Rightclick, "new" -> "boolean": "network.protocol-handler.external.qw" "true"
  • Rightclick, "new" -> "boolean": "network.protocol-handler.warn-external.qw" "false" (unless you want that "are you sure" box)

Common problems

Unlike Windows, Linux is case-sensitive, which means "PaK0.pAk" and "pak0.pak" are different files. If you just copied the Quake directory from your Windows machine, it's possible that there are some files in upper case. Fortunately, that's easy to fix.

  • change to your main quake directory

e.g. 'cd /home/joe/quakeworld'

  • convert every file in your Quake directory (including all subdirectories) to lowercase, run this little script (by faustov@ryba):
#! /bin/bash
#

Cdir ()
{
for elem in * ; do
        if [[ -d "$elem" ]] ; then 
                mv "$elem" "$(echo $elem | sed -e 's/./\L&/g')" 2> /dev/null
                elem=$(echo $elem | sed -e 's/./\L&/g');
                cd "$elem";
                Cdir;
                cd ..;
        else 
                mv "$elem" "$(echo $elem | sed -e 's/./\L&/g')" 2> /dev/null
        fi;
done;
}

Cdir;

Compile ezQuake yourself

You can use GIT to get the latest development sources and compile ezQuake yourself.

Prerequisites

  • A working Internet connection
  • Installed software
    • git (package git)
    • gcc, make... and a sane buildsystem (mainly build-essential)
    • libraries, see below

Procedure

  • change to your home directory
cd ~
  • checkout the code from git to folder ezquake
git clone git://github.com/ezQuake/ezquake-source ezquake
  • install necessary libraries (for Ubuntu)
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev libasound2-dev x11proto-xf86dga-dev x11proto-xf86vidmode-dev libxxf86dga-dev libxxf86vm-dev libxext-dev libsvga1-dev libxpm-dev
  • for OpenSUSE
sudo zypper install freeglut-devel alsa-devel
  • change to libs directory
cd ezquake/libs/linux-x86/ (or linux-x86_64 for 64bit)
  • invoke a script downloading precompiled versions
 ./download.sh 

cd ../../
  • compile the OpenGL binary
make glx
  • (optional) Software version SVGA (32bit only)
make svga
  • (optional) Software version X11
make x11

If everything went smoothly, your freshly compiled binary can be found in release-x86/ezquake-gl.glx (or release-x86_64/ dir for 64bit)
