Should I stick with vesa driver or try another one

Z0K4 · Post by **Z0K4** » 17. Sep 2011, 17:14

Hi guys... I'm using computer with Intel's GMA4500 integrated graphics chip, and I'm wondering: should I leave the vesa driver that came with the kernel, or should I install a propriatory (source provided by Intel) driver, and which one of Intel's drivers to use (example i810). Where can I find tarballs of this drivers? By the way it's Salix64 13.37!

Thank you, and cheers!

Are you sure you use the vesa driver?
what is the output of dmesg |grep drm and dmesg |grep agp ?

Hi! The outputs of those commands are:

Code: Select all

dmesg | grep drm
[    7.839322] [drm] Initialized drm 1.1.0 20060810
[    8.606151] [drm] MTRR allocation failed.  Graphics performance may suffer.
[    8.933546] fb0: inteldrmfb frame buffer device

[    9.735133] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0

Initialized i915! Does this mean I'm using i915 driver? If so, why do I only have xorg.conf-vesa file in the /etc/X11/ folder and not xorg.conf?
I'm asking this because I want to enable 3D acceleration. Could it be it's already enabled by default?

Thank you for your time djemos! Cheers!

Having xorg.conf-vesa in /etc/X11/ folder means nothing. It is a sample. If you want to use vesa then have to cp /etc/X11/xorg.conf-vesa to /etc/X11/xorg.conf. Of cource don't do this.
You use i915 drive. New xorg does not need a xorg.conf file anymore.

Read this http://ftp.ntua.gr/pub/linux/slackware/ ... _HINTS.TXT
You can read there The version of Xorg in Slackware 13.37 will not (in most cases) require an
/etc/X11/xorg.conf file.

The version of Xorg in Slackware 13.37 will not (in most cases) require an 
  /etc/X11/xorg.conf file.  Input hotplugging is no longer done using hal; 
  instead, it now uses udev for input device detection and keyboard mapping.

  /usr/share/X11/xorg.conf.d/ is the "packaged" configuration directory; all
  files ending with ".conf" in this directory are used by the X server 
  unless there is an identically-named file in the local sysadmin directory.
  The local sysadmin config directory is /etc/X11/xorg.conf.d/ - all files
  ending with ".conf" in this directory are parsed.  

  There are several default config files in /usr/share/X11/xorg.conf.d/:
    * 10-evdev.conf
        a "catchall" file for input devices using the evdev driver; this 
        should work for most hardware in the absence of a better driver
    * 50-synaptics.conf
        overrides the earlier 10-evdev.conf file and uses the synaptics 
        driver for all touchpads
    * 50-wacom.conf
        overrides the earlier 10-evdev.conf file and uses the wacom driver 
        for Wacom tablets
    * 90-keyboard-layout.conf
        this sample ("normal" en layout) keeps the "old" default of 
        allowing Zap'ing the Xserver.
  If you need to modify any of these defaults, then copy the relevant file
  from /usr/share/X11/xorg.conf.d/ to /etc/X11/xorg.conf.d/ and edit the
  copy.
 
  You can still create an xorg.conf file if you wish, or you can create some
  minimal xorg.conf snippets with only the specific contents that you wish
  to override (as an example, to use a binary-only video driver) as separate
  files in the /etc/X11/xorg.conf.d/ directory.

I suppose that you use Salix64 13.37 xfce edition.

To be sure check the output of glxinfo command.
Also glxgears. I think 3d acceleration is enabled.

About the message "MTRR allocation failed. Graphics performance may suffer."
check the output of cat /proc/mtrr

Mine is

Yes it's Salix64 Xfce edition.

Output of glxgears:

Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.

I've read somewhere that with enabled 3D acceleration it should be 1000+ FPS. Is this true?

I don't know.
I know that 3D acceleration is enabled and you can use it.

Also read the private message in this forum, i have send you. Run the script and check again.

OK. After running this scrip:

Code: Select all

#!/bin/sh
address=`lspci -v \
	| grep -A 7 VGA\
	| grep -F " prefetchable"\
	| awk 'BEGIN{OFS="";ORS=""}
	      {print $3
	      i = length($3)
	      while(i<8){
	      		print 0
	       		i++
	       }}'`

hsize=`lspci -v \
	| grep -A 7 VGA \
	| grep -F " prefetchable" \
	| awk '{print $6}' \
	| sed 's/[^0-9]//g' \
	| awk 'BEGIN {OFS = "";ORS=""}
	       { printf "%x" , $1
		 i = length($1)
		 while (i<8) {
		 	print 0
		 	i++
		 } }'`

echo "base=0x$address size=0x$hsize type=write-combining"

I get this as output:

Code: Select all

base=0xc0000000 size=0x10000000 type=write-combining

And after running this script:

This is output of cat /proc/mtrr:

3D acceleration is working in your system. Just use it.
