[SOLVED by panning] Force 1024x768 on 1024x600 notebook

[rpsr1994]

Hello,

I have recently installed Linux Mint 15 "Olivia" (MATE Desktop) on my Asus EeePC 1001-PX which only supports a maximum resolution of 1024x600.

However, there are many things that get hidden out of screen that I can't access by any means (some are settings I would like to change, others are options in applications I have to use, etc).

I previously had Windows installed (I know I'm crazy) but the truth is that I could force a 1024x768 resolution on Windows (even though the pixels would vertically be kind of messed up because of the 168 pixel increase).

I have searched for answers but found none that worked. I think maybe I have to install different graphic drivers?

In case someone wants to know, here is the output of inxi -Gx:

Code: Select all

Graphics:
    Card: Intel Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller

    GLX Renderer: Mesa DRI Intel IGD x86/MMX/SSE2

And here is the output of xrandr -q:

Try this tutorial, but change code 'VGA1' to "LVDS1"

Screen 0: minimum 320 x 200, current 1024 x 600, maximum 32767 x 32767
LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 223mm x 125mm
1024x600 60.2*+
800x600 60.3 56.2
640x480 59.9

[rpsr1994]

I have tried the tutorial, but when I got to execute:

Code: Select all

xrandr --addmode LVDS1 1024x768_60.00

I got:

Code: Select all

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  25
  Current serial number in output stream:  26

And I can't do anything else from the tutorial afterwards. However I did notice a change when I run xrandr -q:

Code: Select all

So I am not sure what's happening.

[wayne128]

not sure too

but reading this

VGA1 disconnected (normal left inverted right x axis y axis)
1024x768_60.00 (0x11c) 63.5MHz

made me wonder if you are typing VGA1..instead of LVDS1...

perhaps just post terminal output of each line following the tutorial.

[rpsr1994]

Ok, so following the tutorial:

xrandr:

   800x600        60.3     56.2  
   640x480        59.9

cvt 1024 768:

(no output)

xrandr --addmode LVDS1 1024x768_60.00:

  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  25
  Current serial number in output stream:  26

It happened again...

[Mark Phelps]

When you run xrandr, it lists the modes that it supports -- and you can't set it to a mode NOT in that list, sorry.

[rpsr1994]

Is there no way to force the resolution? Maybe by installing a different driver or something?

I like Linux way more than I will ever like Windows (and there is the performance aspect in my old laptop), but the truth is that some tools I need to use have certain problems in a resolution lower than 1024x768, so I really needed to force this resolution.

[Mark Phelps]

You can try the Intel link, but there may not be a driver you can use: https://downloadcenter.intel.com/Detail ... 5&lang=eng

[AlbertP]

Please don't try installing an Intel driver by hand that way. All you need is preinstalled.

You might need to add quotes to 1024x768_60.00, i.e. "1024x768_60.00" in the xrandr --addmode command. It is showing you invalid parameter, i.e. you are giving arguments that aren't correct.

Note that you need to run xrandr --newmode again before trying to do this. The --newmode doesn't persist by default. We can make it persist, if the mode turns out to work.

If you get the mode added after all, but the display shows out of range, black screen or something else that's too weird, you may need to generate the mode with cvt -r instead of cvt.
Some flatpanel are made to work with CVT-RB modes generated with the -r option. This option is limited to 60Hz refresh rate, but your screen does not support any other refresh rate - if it did, it for sure wasn't using CVT-RB.

[rpsr1994]

Did the tutorial again, this time using the quotes in the --addmode, but the error still came up

Code: Select all

xrandr --addmode LVDS1 "1024x768_60.00"
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  25
  Current serial number in output stream:  26

[AlbertP]

It is possible to pan the desktop to 1024x768 pixels: http://techfrp.blogspot.nl/2010/09/xrandr-desktop-scaling-for-ubuntu.html

Eventually you could also apply a scaling factor by adding --scale 1x1,28 to the command, to make the 1024x768 desktop fit on your netbook's monitor.
(768 pixels is 1,28 times 600)

[rpsr1994]

The panning option works, so thanks a lot !

Tried the scale option as well, but a black bar appeared covering the additional 128 pixels, and nothing can enter it. The output message from xrandr was:

Code: Select all

xrandr: specified screen 1280x600 not large enough for output LVDS1 (1024x768+0+0)

EDIT: My bad, forgot to edit the resolution (and for some reason it got 1280 instead of 1024), but even with the correct values the applications don't display correctly
