Hi. I am new to slackware. I installed slack on my new
acer extenza 5620z after some search and research.
Still have some problems.
Will start with 2 of them:

1. I have success starting x server with 1280x800 resolution,but i have a doubt in options HorizSync and VertRefresh.
What i did - just cut and past this lines from my suse
partition. Is it ok? Do i have to type it? Can it damage my laptop screen? I couldn't find this info on the acer site or in the manuals. I don't now where to find this info.

xorg:

2. xorg configured by default with vesa driver instead of "intel". Is it ok?
If i will run 3d or compiz - will it work?

lspci
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

Thanks.

1. If it worked in SUSE without a problem then it'll work in Slackware without a problem. A lot times it's easier to copy an automatically configured xorg.conf and then edit it as needed like you did.

2. Compiz wont work with VESA, well, if it does it wont work well. You'll need to configure your video card to use the Intel drivers and make sure it's running with DRI enabled.

Hi, CrEsPo.
Thank for quick reply.
1. I need to install driver for "intel" first, wright?
If yes, i will search for some info about how to...
2. "make sure it's running with DRI enabled" - don't know hat it means,
but i will find out.

thanks.

DRI is direct rendering infrastructure. Here's how to enable it (follow the guide for i810, it should work):
http://www.linuxquestions.org/questi...in-x11-402003/

If you want, running 'xorgsetup' or 'xorgcfg' can oftentimes auto detect refresh rates properly ... usually not for laptops tho.

H_TeXMeX_H, thanks for a link.

There is one thing i can't find - if i want to run xorg with
"intel" driver - may i just put lines like that:

Section “Device”
Identifier “Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller”
Driver “intel”
Option “DRI” “true”
Option “XVideo” “true”
EndSection

May it work?
How do i know if xorg have intel driver? Is it xf86-video-intel?
If not, how i download it?
I have to get understanding of this.

Thanks for help.

Yeah, read the man pages 'man intel' and 'man i810', in fact they are the same thing (pretty much):

Yes, that's the intel package, there's also the i810 package, both should be installed by default.

Just as a lark, try running `xorgcfg`. Just click on the exit button when it appears, and if the screen looks okay, let it write the two files it wants to.

On new hardware, this usually works a treat.

OK. Thanks for reply.
`xorgcfg` - worked fine. It piked up intel driver as expected
and seems that all another configuration was ok
Now i try to enable DRI. After enable (from the link :
http://www.linuxquestions.org/questi...in-x11-402003/)
i get :
glxinfo

It looks like there's a line in you 'xorg.conf' something like:
Change it to:
Save and try again.

Hi, H_TeXMeX_H.
1. I already have this line:
BusID "0:2:0"
2. Another thing - desktop font looks not so clear.
Maybe some misconfiguration in xorg.conf.
I am not sure.

I will keep checking it.....
Thanks

Note that the Mode line in the DRI section should be '0666' not '0660'.

Everything else seems to be ok. Does direct rendering work now ?

You may be able to find more info on the laptop here:
http://www.acerpanam.com/synapse/for...erPanAm.com/us
click my system information ...

So, is this xorg.conf the one from suse ? If so, maybe try starting with one made by 'xorgcfg' or 'xorgsetup'.

OK. First of all thanks to everyone that help me.
I tried first xorg.conf from suse. It worked cool but no rendering.
Than i tried create xorg with xorgcfg. It was also ok, but still no rendering.

glxinfo | grep rend
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

It my xorg now:
Everithing seems ok here (to me at list )

Try one more thing, and if this doesn't work, I don't know what else to do to enable direct rendering. So for your xorg.conf which you just posted,
First, change the driver from "intel" to "i810", just to see.
Second, in the "Module" section load 'dri' after 'glx', not sure if it has to be this way, but this is the way they are in the HOWTO.

If you're running in "1280x800", that's the native resolution so fonts will look best in that. You can also measure the display area of your screen in milimeters and put that in '#DisplaySize 330 210 # mm', that has helped me some in the past.

OK. It doesn't work. I think maybe problem not in xorg.
In suse direct rendering working fine. The same xorg.config
worked in slack, but without rendering. Anything i tried to
change in xorg file didn't work. So i begin to think it not
in xorg. Maybe it's not a problem i can fix in one day.
I will search for some info. Till now i found a thread about
this problem because of not updated intel drivers.
However, i am not sure how to check if there is update for intel package.
So for now thanks a lot.
I will keep trying.
It is all about not give up from the start.
Am i wright?

I have configured my graphic card; resolution and refresh rate with this instruction:

For me it works
