[Solved]Resolution/Video driver issue

[gabrieles84]

Chipset "i915" works, X strarts but resolution issue remains. This is the xorg i used:

Code: Select all

1440x900 is the resolution of my lcd monitor, so it does support it. J1900 soc can handle that, as done in the past months with other distros i've tryed.

This is xrandr output:

Code: Select all

Very nice!

To get the wanted resolution try the folloing:
add to the end of Section "Monitor" one of the lines:

Modeline "1440x900" 106.50 1440 1520 1672 1904 900 903 909 934 -hsync +vsync
or
Modeline "1440x900" 108.84 1440 1472 1880 1912 900 918 927 946 +hsync +vsync


Then add in Section "Screen" to the end of each SubSection "Display" the line:

Modes "1440x900"

Test both Modelines, if you like or if necessary.

Thank you so much! Now everything works!!! Just a question, i think that this xorg configuration uses xf86-video-intel driver because if i execute "vainfo" i get this output:

Code: Select all

enzo[~]$ vainfo
libva info: VA-API version 0.34.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

how can i modify xorg to use libva drivers?
I installed libva 1.2.1 and libva-intel-driver 1.2.1

Update: I downgrade libva package to 0.31 and i have a different error:

Code: Select all

enzo[~]$ vainfo
libva: libva version 0.31.1-sds1
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I am glad that I could help this far.

Unfortunately, I am not familiar with your particular hardware from Intel or with VA-API. I'm afraid I can not help you much further. The latest Intel chipset, which I used was a i815.

Generally, alternative kernel modules are installed, in which the standard module is black-listed and the new module is installed. In best case this is all done by the installation script. Black-listed modules are listed in configuration files found in /etc/modprobe.d . For a GPU driver module that is used by X, the correct driver and / or the correct chipset must be specified then in xorg.conf . The parameterization in various sections must be adjusted (significantly) too. In best case this is done by the installation script too.

The two message blocks shown mean that vainfo can not work with the expected underlying software components. Presumably they are not present at all or of incorrect version. If no driver names are displayed, as shown in the error messages, the driver are probably not loaded or the Libs do not fit. You wrote in previous post: I've installed libva and libva-intel-driver. Until you can prove that you have performed a successful installation of an Intel GPU driver (you wrote: intel official driver), I believe that the standard Linux/Xorg driver for Intel hardware is loaded furthermore.

Thank you so much for helping me out and for the explanation! I'll try some experiment!
