3 By default, SliTaz v3 uses Xorg 7.4 with the //xorg-xf86-video-vesa// v2.0.0 driver. This basic driver can cause problems with certain hardware combinations and can sometimes result in a very low resolution. Occasionally, X does not start at all and instead falls back to the log-in screen or to a text-based prompt. There are some simple solutions that can yield major improvements:

5 * check that you have enough RAM to run the default ISO. If not, use the [[http://mirror.slitaz.org/iso/3.0/flavors/|Low RAM ISO]] instead.
|
|
slaxemulator@7
|
6 * try the [[http://mirror.slitaz.org/iso/3.0/flavors/slitaz-3.0-xvesa.iso|XVesa ISO]] (a.k.a. TinyX)
|
|
slaxemulator@7
|
7 * install a more specific driver for your graphics card
|
|
slaxemulator@7
|
8 * customise your Xorg configuration file (//xorg.conf//)

12 <note tip> Up to v7.3, the Ctrl+Alt+Backspace key combination could be used to quit the X server. To enable it in version 7.4 and later, type the following command from any X terminal emulator:
|
|
slaxemulator@7
|

|
|
slaxemulator@7
|
14 <code>setxkbmap -option terminate:ctrl_alt_bksp</code>

23 ===== Using Xorg & Vendor-Specific Drivers =====
|
|
slaxemulator@7
|
24
|
|
slaxemulator@7
|
25 When you are using SliTaz as your main system, it's recommended to use Xorg over XVesa. You will get a much better display and performance than when using Xvesa tinyX.

28 === AGP Cards ===
|
|
slaxemulator@7
|
29
|
|
slaxemulator@7
|
30 All AGP video cards need extra kernel modules to function under Xorg. Check if you have an AGP video card with //lspci//; if so, install the necessary modules in the //linux-agp// package before using Xorg:
|
|
slaxemulator@7
|
31
|
|
slaxemulator@7
|
32 <code>
|
|
slaxemulator@7
|
33 # tazpkg get-install linux-agp
|
|
slaxemulator@7
|
34 </code>
|
|
slaxemulator@7
|
35
|
|
slaxemulator@7
|
36 Load the modules using the SliTaz hardware detection tool:
|
|
slaxemulator@7
|
37
|
|
slaxemulator@7
|
38 <code># tazhw detect-pci</code>
|
|
slaxemulator@7
|
39
|
|
slaxemulator@7
|
40 You can now use the SliTaz X configuration tool to detect your settings:
|
|
slaxemulator@7
|
41
|
|
slaxemulator@7
|
42 <code># tazx</code>
|
|
slaxemulator@7
|
43
|
|
slaxemulator@7
|
44 Select the appropriate driver for your video card from the list.
|
|
slaxemulator@7
|

|
|
slaxemulator@7

|
|
slaxemulator@7
|
47 === DRI / DRM Problem ===
|
|
slaxemulator@7
|
48
|
|
slaxemulator@7
|
49 Sometimes, the auto-detection is not enough. Cards that require [[http://www.bitwiz.org.uk/s/how-dri-and-drm-work.html|DRI / DRM]] are supported under SliTaz, but v3 has a couple of bugs! The file ///dev/dri// should be a directory and not a file and, to get DRI working correctly, we have to add tux to the group video or modify permissions in the Xorg configuration file:
|
|
slaxemulator@7
|
50
|
|
slaxemulator@7
|
51 <code>
|
|
slaxemulator@7
|
52 # tazpkg get-install linux-drm
|
|
slaxemulator@7
|
53 # tazpkg get-install mesa-demos (for glxinfo and glxgears)
|
|
slaxemulator@7
|
54 # rm /dev/dri
|
|
slaxemulator@7
|
55 # mkdir /dev/dri/
|
|
slaxemulator@7
|
56 # addgroup tux video
|
|
slaxemulator@7
|
57 </code>
|
|
slaxemulator@7
|
58
|
|
slaxemulator@7
|
59 The //drm// module is not loaded by //tazhw// so you have to do it manually:
|
|
slaxemulator@7
|
60 <code># modprobe drm</code>
|
|
slaxemulator@7
|
61
|
|
slaxemulator@7
|
62 <note tip>All modules, which are loaded by tazhw and yourself to make your changes permanent, have to be added to the SliTaz Control Box under Initialization in "Load Modules". </note>

65 === Intel cards ===
|
|
slaxemulator@7
|
66
|
|
slaxemulator@7
|
67 The xorg-xf86-video-vesa 2.0.0 driver has a lot of trouble with Intel chips. For example, on a 82945GM chipset it does not display 1280x1024 and 1024x768, but 1600x1200 is not a problem.
|
|
slaxemulator@7
|
68
|
|
slaxemulator@7
|
69 Use "tazx" to select the intel driver, then "tazhw detect-pci", solve the dri problem and load drm and restart X - normally that's it (perhaps you must change your xorg.conf too).
|
|
slaxemulator@7
|
70
|
|
slaxemulator@7
|
71 Some users may need to add the "intel_agp" module to the xorg.conf file:
|
|
slaxemulator@7
|
72
|
|
slaxemulator@7
|
73 <file>
|
|
slaxemulator@7
|
74 Section "Module"
|
|
slaxemulator@7
|
75 ...
|
|
slaxemulator@7
|
76 Load "intel_agp"
|
|
slaxemulator@7
|
77 ...
|
|
slaxemulator@7
|
78 EndSection
|
|
slaxemulator@7
|
79 </file>
|
|
slaxemulator@7
|
80
|
|
slaxemulator@7
|
81 for the driver to work.
|
|
slaxemulator@7
|
82
|
|
slaxemulator@7
|
83 Depending on the hardware, the //mode-setting// feature must be turned on or off. To turn it off append one of the following to the //kernel// line in the GRUB boot-loader configuration:
|
|
slaxemulator@7
|
84
|
|
slaxemulator@7
|
85 * //nomodeset//
|
|
slaxemulator@7
|
86 * //i810.modeset=0//
|
|
slaxemulator@7
|
87 * //i915.modeset=0//
|
|
slaxemulator@7
|
88
|
|
slaxemulator@7
|
89 If mode-setting is off by default and should instead be turned on, append one of the following:
|
|
slaxemulator@7
|
90
|
|
slaxemulator@7
|
91 * //modeset//
|
|
slaxemulator@7
|
92 * //i810.modeset=1//
|
|
slaxemulator@7
|
93 * //i915.modeset=1//
|
|
slaxemulator@7

95 === Trident cards ===
|
|
slaxemulator@7
|
96
|
|
slaxemulator@7
|
97 Use "tazx" to select the trident driver, install mesa-dri-trident
|
|
slaxemulator@7
|
98 <code># tazpkg get-install mesa-dri-trident</code>and restart X
|
|
slaxemulator@7
|

101 === nVidia cards ===
|
|
slaxemulator@7
|
102
|
|
slaxemulator@7
|
103 SliTaz provides automatic configuration for nVidia cards. There are two drivers available, the Xorg-provided //[[#free-driver-nv|nv]]// and the nVidia-provided, non-free //[[#non-free-driver-nvidia|nvidia]]//. The //nv// driver should be tried first as this has been compiled for SliTaz, whereas the nVidia-supplied driver is a //binary blob// that tries to fit each and every Linux distribution.

slaxemulator@7
|
128 To set-up the non-free nVidia drivers, use the SliTaz Hardware Configuration tool with the //--non-free// switch:
|
|
slaxemulator@7
|
129 <code># tazhw setup nvidia --non-free </code>
|
|
slaxemulator@7
|
130

142 * Attempt to configure the card with nVidia's tool:
|
|
slaxemulator@7
|
143 <code># nvidia-xconfig</code>
|
|
slaxemulator@7
|
144 * To test if rendering is working,
|
|
slaxemulator@7
|
145 <code># glxinfo | grep render</code>
|
|
slaxemulator@7
|
146 * To change nVidia's settings, use nVidia's Settings tool:
|
|
slaxemulator@7
|
147 <code># nvidia-settings</code>
|
|
slaxemulator@7
|
148
|
|
slaxemulator@7
|
149 == Hiding the Logo ==
|
|
slaxemulator@7
|
150 To hide the nVidia logo when the system boots, add the following to ///etc/X11/xorg.conf// at the end of the //Device// section:
|

154 === ATI cards ===
|
|
slaxemulator@7
|
155
|
|
slaxemulator@7
|
156 SliTaz provides automatic configuration for ATI cards. There are two drivers available, the Xorg-provided //[[#free-driver-radeon|radeon]]// and the ATI-provided, non-free //[[#non-free-driver-catalyst|catalyst]]//. The //ati// driver should be tried first as this has been compiled for SliTaz, whereas the ATI-supplied driver is a //binary blob// that tries to fit each and every Linux distribution.

|
|
slaxemulator@7
|
160
|
|
slaxemulator@7
|
161 To set-up the free ATI drivers, install the AGP & DRM modules, then use the SliTaz Hardware Configuration tool:
|
|
slaxemulator@7
|
162
|
|
slaxemulator@7
|
163 <code># tazpkg get-install linux-agp
|
|
slaxemulator@7

|
slaxemulator@7
|
165 # tazhw setup ati</code>
|
|
slaxemulator@7
|
166
|
|
slaxemulator@7
|
167 - but perhaps this is not enough - check /var/log/Xorg.0.log to see if other modules must be loaded: See [[#dri-drm-problem | DRI / DRM Problem ]]
|
|
slaxemulator@7
|
168
|
|
slaxemulator@7
|
169 Alternatively, you can do this process manually:
|
|
slaxemulator@7

171 * xorg-xf86-video-ati mesa-dri-ati mesa-demos linux-agp
|
|
slaxemulator@7

179 <code># tazhw detect-pci</code>
|
|
slaxemulator@7
|
180
|
|
slaxemulator@7
|
181 * To install the free ATI driver radeon, replace //vesa// with //radeon// in the ///etc/X11/xorg.conf// file:
|
|
slaxemulator@7
|
182 <code># sed -i 's/vesa/radeon/' /etc/X11/xorg.conf</code>

191 === Modifying the Xorg Configuration ===
|
|
slaxemulator@7
|
192
|
|
slaxemulator@7
|
193 Normally Xorg will start successfully, but perhaps not with the correct resolution. See the [[#adding-resolutions|tips]] at the end of this page or sometimes search the Internet for the xorg.conf for your card and your monitor - or use another LiveCD and copy the working configuration file to SliTaz.

196 ===== Configuring X =====
|
|
slaxemulator@7
|
197
|
|
slaxemulator@7
|
198 While X will do it's bets to auto-configure itself for your graphics card set-up, sometimes it needs a tweak. Its configuration file, ///etc/X11/xorg.conf//, is the place to customise the configuration. The best example of this is switching drivers or adding resolutions it doesn't detect.

266 === Restarting Xorg ===

268 For changes to take effect, you need to restart Xorg. This can be done by logging out of your session and back in again. Choose //Logout// from the Menu and select the //Logout X session// button. If you see the Slim log-in manager, Xorg has restarted successfully!

271 ===== Using XVesa and Generic Drivers (TinyX) =====

273 The [[http://mirror.slitaz.org/iso/3.0/flavors/slitaz-3.0-xvesa.iso|SliTaz-3.0-xvesa.iso]] uses the XVesa system instead of Xorg, which offers a more generic driver at the cost of performance. It boots on nearly all computers and laptops, but can only display a 4:3 resolution.

275 To find out which resolutions are possible with your card, type:
|
|
slaxemulator@7
|
276
|
|
slaxemulator@7
|
277 <code># Xvesa -listmodes</code>
|

290 This output shows widescreen resolutions cannot be displayed with XVesa.
|
|
slaxemulator@7
|
291
|
|
slaxemulator@7
|
292 If X does not start with the default SliTaz ISO, you could use the XVesa ISO to install your default Xorg driver. When you are asked for your resolution at boot-time, scroll down the window and find the option to install your Xorg driver //before// XVesa is started. However, don't use "tazx" and "tazhw setup ati or nv" on the XVesa ISO to install your Xorg driver because you will end up with a blank and confused screen!
