Changing resolution and refresh rate in Slackware 11.0

**noobslacker** · 11-26-2006

I've been trying to figure out how to change my resolution to 1280x1024 at 80Hz. I read other posts about how to do this but my xorg.conf doesn't list resolutions like the other xorg.conf files I looked at. I also have no i idea about how to change the refresh rate.

This is the monitor im using
http://www.viewsonic.com/support/des...91fplus/#specs

My video adapter is built into my motherboard and im not sure what it is. What happened to superprobe? Is there a replacement?

This is my xorg.conf as created by xorgsetup:

Code:

bump, post was on second page

how can nobody know how to change resolution and refresh rate?

Your xorg.conf looks very different than mine. For one thing, I'm not seeing the resolution section in yours either. Is that how your xorg.conf appeared the first time you looked at it? Here's the resolution section from mine...

Code:

# "1024x768" is also a conservative usable default resolution.  If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)

    Subsection "Display"
        Depth       8
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       32
        Modes "1024x768" "800x600" "640x480"
    EndSubsection

EndSection

...and that's where you set the different resolutions. If you need it, I can post my xorg.conf and you can configure it from scratch for yours. Let me know...

That's cause the installer used xorgsetup instead of xorgconfig

Just run xorgconfig and you'll get a normal config file.

jens! You've been gone for a while! I see you're back in full force...

**noobslacker** · 12-18-2006

I can't get xorgconfig to create a xorg.conf file that works, I've tried it tons of times doing things differently. I have no idea what driver to select, how much memory the card has of how to find out. What happened to superprobe? is there a replacement?

**noobslacker** · 12-21-2006

I know how to use xorgconfig but I have no idea how to configure it without any specs. I don't know the speed, amount of memory, the manufacturer or what driver it uses. The only thing I know about it is that its a VGA video card built into the motherboard. How do I figure these things out?

Thanks in advance for the help.

I used lspci to find this out:

Code:

# lspci -vvv -s 00:01.0

00:01.0 VGA compatible controller: Intel Corporation 82810E DC-133 CGC [Chipset Graphics Controller] (rev 03) (prog-if 00 [VGA])

        Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 0
        Interrupt: pin A routed to IRQ 3
        Region 0: Memory at 44000000 (32-bit, prefetchable) [size=64M]
        Region 1: Memory at 40100000 (32-bit, non-prefetchable) [size=512K]
        Capabilities: [dc] Power Management version 1
                Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

How do I figure out what card and how much memory to specify when using xorgconfig?

How do I figure out what card and how much memory to specify when using xorgconfig?

If you're unsure about your hardware, it might be easier to use some safe defaults. Live CDs can give you an easy example on how to change it(xorg.conf) later.
You really should ask your hardware vendor about all the details (non of the probing tools are perfect).
