Xorg resolution

[osjbe]

Dear Gurus,

I installed TinyCore through the Core+ CD on a partition of a vintage Sony Vaio computer (PIII, 1.86 GHz, RAM=2GO). This computer is capable of 1280x800 resolution. Graphic card is [AMD/ATI] RV410/M26 [Mobility Radeon X700].
The 1280x800 resolution is used when installing out of the box WinXP, Lubuntu 14.4, Puppy Linux and Vector Linux. By contrast Tiny Core (with Vesa) is using 1024x768 (even if I try to add 1280 800 to the first line in .xsession) hence circles turn into ellipses.

I did install Xorg and again under Xorg I could not succeed to get 1280x800 resolution
onboot.lst contains inter alia :
...lxrandr.tcz
firmware-radeon.tcz
Xorg-fonts.tcz
Xorg-7.7.tcz
xf86-input-evdev.tcz
xf86-video-amdgpu.tcz

I have added to xorg.conf.d
10-amdgpu.conf:

Code: [Select]

Section "OutputClass"
Identifier "AMDgpu"
MatchDriver "amdgpu"
Driver "amdgpu"
EndSection
and 10-monitor.conf:
Section "Monitor"
    Identifier             "Monitor0"
EndSection
Section "Device"
    Identifier             "Device0"
    Driver                 "amdgpu" #Choose the driver used for this monitor
EndSection
Section "Screen"
    Identifier             "Screen0" 
    Device                 "Device0"
    Monitor                "Monitor0"
    DefaultDepth           24
    SubSection             "Display"
        Depth              24
        Modes              "1280x800_59.90"
    EndSubSection
EndSection
and X does not show at atart of Tiny Core.
If I remove 10-monitor.conf X opens but not surprisingly with the 1024 resolution.

I have added to /etc/X11/xorg.conf the content of 10-monitor.conf above, X does open (with 1024 resolutions) only if I comment (#) the Driver line in Section Device.

Can you give me a hint at what I should do ? Thanks in anticipation.

[malikawan]

Have you tried xrander

[osjbe]

yes I did, 1024x768 is the highest resolution available.

[Juanito]

Did you try xf86-video-ati?

You could also try without xf86-video-anything to see if the built-in modesetting driver gives you the resolution you need.

If you take a look at /var/log/Xorg.0.log you should be able to see which drivers Xorg tries to use and in what order.

[curaga]

amdgpu is the driver for Radeon HD8000 and newer cards. You need xf86-video-ati.

[osjbe]

Thank you for your feed back. I have added xf86-video-ati.tcz to onboot.lst but still I cannot get 1280x800 resolution.
Below is part of Xorg.0.log

tc@box:/var/log$ more Xorg.0.log | grep driver

maybe interesting to note is xrandr result

Code: [Select]

tc@box:~$ xrandr --addmode default  1820x800_59.90
xrandr: Failed to get size of gamma for output default
xrandr: cannot find mode "1820x800_59.90"
What should I do next ? Thanks.

[osjbe]

I tried without any xf86-video-anything as advised and got 1024x768 resolution.

[Juanito]

When using xf86-video-ati, do you get a message further down in Xorg.0.log that the driver has been unloaded due to an error or missing file?

Is the 1280x800 resolution mentioned anywhere in Xorg.0.log?

[osjbe]

Below two conditions :

One with /etc/X11/xorg.conf like this :

Code: [Select]

Section "Monitor"
    Identifier             "Monitor0"
EndSection

#Section "Device"
#    Identifier             "Radeon"
#    Driver                 "ati" #Choose the driver used for this monitor
#EndSection

Section "Screen"
    Identifier             "Screen0"  #Collapse Monitor and Device section to Screen section
    Device                 "Radeon"
    Monitor                "Monitor0"
    DefaultDepth           24 #Choose the depth (16||24)
    SubSection             "Display"
        Depth              24
        Modes              "1280x800_59.90" #Choose the resolution
    EndSubSection
EndSection
in Xorg.0.log I see :

[Juanito]

You could try xf86-video-ati + graphics-KERNEL without the xorg.conf snippets?

[osjbe]

It works perfectly, thank you very much, I am very grateful Juanito .
