Hello there,

I am having a Notebook with an SiS 771/671 Graphic Chip. I have some troubles to get the natve resolution (1280x800) of it.
Everytime when I start my Xserver (Xorg 1.4.0.90-r3) I only get the resolution 1024x768.
In the xorg.conf, I use the vesa driver with the following configuration:
Code:
Section "Device"
        Identifier      "VGA"
        Driver          "vesa"
        VendorName      "Silicon Integrated Systems [SiS]"
        BoardName       "771/671 PCIE VGA Display Adapter"
#       BusID           "PCI:01:00:0"
EndSection

Section "Monitor"
        Identifier      "LCD"
        VendorName      "Plug'n Play"
        Option          "DPMS"  "Off"
        HorizSync       31-65
        VertRefresh     56-75
#       Modeline        "1280x800_60.00"  83.46  1280 1344 1480 1680  800 801 804 828  -HSync +Vsync
EndSection

Section "Screen"
        Identifier      "Screen"
        Device          "VGA"
        Monitor         "LCD"
        DefaultDepth    24
        SubSection "Display"
                Depth           24
                Modes           "1280x800" "1280x768" "1024x768" "800x600" "640x480"
                ViewPort        0 0
        EndSubSection
EndSection

As you can see in the config above, I comment out some lines. I also tried it with the lines, but it won't work.

Does everone know how to solve this issue?


Thanks in advance,
Marko

I also have the same graphics card in an Esprimo Mobile V5535:
Code:
# lspci
01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10)


I have been able to get the 1280x800 resolution by using the sis driver. I have written the configuration in the Gentoo Wiki.

I get the following messages in /var/log/Xorg.0.log:
Code:

Heya, which sis driver where you using? Sadly the wiki article isn't available any more :(

Thanks!

linux-tux,

The vesa driver, while it works on all graphics cards produced since 1998 only provides vesa standard 4:3 resolutions.
I will not support any wide screen resolutions.

The sis driver should work for your card
Code:
emerge x11-drivers/xf86-video-sis
and change driver "vesa" to driver "sis" in xorg.conf.
I think the sis driver supports DRI too, so you can have some hardware acceleration.

No, the xf86-video-sis driver doesn't support these specific cards. There's some 2d-only binary-only driver around, but while reading mimosinnet's post i thought there might be. But the recovered wiki page clearly states that he was using the 2-d binary-only driver which has been made available for ubuntu 7.10/8.4 and Fedora 9 some time ago.

linux-tux,

In view of what dertobi123 said, you may want to try coaxing the vesa driver to do non vesa standard resolutions.
You can do this by defining your own modelines like this

Sorry I missed this thread...

Just in case it is helpful to somebody-else:

As dertobi123 says, I have been able to use the 2d-only binary-only driver. I
am able to get xinerama and different resolutions. This is the rellevant part
of my xorg.conf:

Code:
Section "Device"
   Identifier     "Device0"
   Driver         "sis"
   VendorName     "Silicon Integrated Systems [SiS]"
   BoardName      "771/671 PCIE VGA Display Adapter"
   BusID      "PCI:1:0:0"
   Option       "EnableSiSCtrl" "yes"
   Option       "DRI" "off"
   Option       "MergedFB" "auto"
#   Option       "MetaModes" "1280x1024-1280x800 1280x800-1024x768 1024x768-1280x800 1280x800 800x600"
   Option       "MetaModes" "1280x1024-1280x800 1280x800-1024x768 1024x768-1280x800"
   Option      "MergedNonRectangular" "on"
#   Option       "MergedDPI" "100 100"
EndSection


I have got some of these options from
Thomas Winischhofer web
page
. There is also this
page on 2D hardware acceleration
.

NeddySeagoon, thanks for the information on coaxing the vesa driver. I vaguely
remember playing with the modelines without much success. I should try
again. Would it be possible to have xinerama?

Cheers!
