Resolution help... again.

[TheFreeman04]

I posted here yesterday asking about some help with the resolution on my pi; I changed the config file; it now looks like this:

Code: Select all

hdmi_group=2
hdmi_mode=16
overscan_left=15
overscan_right=15

So the resolution is supposed to be 1024x768 but it comes out as 930x704
I'd like to have it as 1280x1024 but it doesn't show any image on the screen when i set this in the config file:

Code: Select all

hdmi_group=2
hdmi_mode=35

Any help guys?

The long way is to check the EDID (and use edidparser) on your screen to check all the possibilities (there is another thread started by Gert on this somewhere). The short way is probably to add
framebuffer_width=1024
framebuffer_height=68
to your config.txt

[TheFreeman04]

It didn't make any difference I'm still getting 930x704. Anything else i can do?

[redcatster]

i tried setting up the config.txt with all sorts of things but it doesn't do anything.
what i'm not sure of is this for cmdline or xwindows.
i know in the past i've had to use a script for xwindows to generate the right xorg.conf for me
i haven't sat down and done a manual setup of a xorg.conf file yet but i think this is what i'm after and maybe everyone else

@TheFreeman04
update your firmware (e.g. with Hexxeh's rpi-updater) and then try dukla2000 suggestion.

[TheFreeman04]

I'm getting no where the hexxeh updater doesn't work all i get is /usr/bin/rpi-update persmision denied, even if i run as root. when i do "sudo su rpi-update" all i get is "Unknown id: rpi-update"
This sucks any more help would be greatly appreciated!

[dom]

We you either want to:
sudo rpi-update

or
su
(type in root password)
rpi-update

[TheFreeman04]

After having a lot of trouble updating; having to re-format my sd card 3 times because it stopped working somehow... I got to update, updated my config file and nothing changed. I checked my compatible modes using "/opt/vc/bin/tvservice -m CEA" and "/opt/vc/bin/tvservice -m DMT" Nothing has changed.

[dom]

So from Pi can you show output of:
/opt/vc/bin/tvservice -s
cat /boot/config.txt

and explain what the resolution you are getting is, and what you expect.

[TheFreeman04]

/opt/vc/bin/tvservice -s shows "state 0x120001, 1024x768 @ 60hz progressive"
My config file looks like this:
hdmi_group=2
hdmi_mode=16
overscan_left=15
overscan_right=15
framebuffer_width=68
framebuffer_height=1024
I would like to have:
hdmi_group=2
hdmi_mode=36
But it doesn't work. The current output resolution (whats actually appearing on my screen) 930x704

[dom]

I don't think you have the latest firmware. Can you report output of:
/opt/vc/bin/vcgencmd version

Well there's your problem. It's six weeks old. You should get:

May 31 2012 13:35:03
Copyright (c) 2012 Broadcom
version 317494 (release)

Please run Hexxeh's rpi-update.

[TheFreeman04]

Damn. I ran it twice yesterday, first time i got a kernel panic. Just done it again, and now it says "fatal: Not a git repository: '//root/.rpi-firmware/.git'"
I am so sorry for this taking so long too sort out, I have never had this many problems at once
Thanks again for any help!

[dom]

Can you show output of the following commands:

md5sum /usr/bin/rpi-update
ls -l /usr/bin/rpi-update
rpi-update

[TheFreeman04]

md5sum /usr/bin/rpi-update:
#1a0e4e39f2497116ffd9e5fb4bcddd0e /usr/bin/rpi-update
ls -l /usr/bin/rpi-update:
-rwxr-xr-x 1 root root 5574 jun 3 1353 /usr/bin/rpi-update
rpi-update:
fatal: Not a git repository: '//root/.rpi-firmware/.git'

[dom]

Your rpi-update file is good.

However I get this output:
pi@raspberrypi:~$ sudo rpi-update
Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS
Performing self-update
Autodetecting memory split
Using ARM/GPU memory split of 128MB/128MB
We're running for the first time
Setting up firmware (this will take a few minutes)

There's something wrong with the other tools. Have you changed default shell? Anything else you've changed from defaults?
I can only suggest you try with a fresh debian image.

[TheFreeman04]

OK, I've got the update to work (finally after a fresh image, thanks ) and now I've lost all modes in DMT is there anything else I can do, or do i just have to deal with it?

[TheFreeman04]

And i'm still getting weird resolutions, even after messing with framebuffer

[TheFreeman04]

After disabling overscan, i am able to get the resolutions i expect; but i'm still not getting the resolutions that 'fit' my monitor (1152x865 or 1280x1024) both of which are in DMT which after the update has "0 modes"...

[dom]

Can you report:
cat /boot/config.txt
/opt/vc/bin/tvservice -s
/opt/vc/bin/tvservice -m DMT
/opt/vc/bin/tvservice -m CEA
/opt/vc/bin/tvservice -d edit.dat (and post edid.dat here)

[TheFreeman04]

My monitor isn't even capable of 1080p/i its a 17" lg flatron maximum resolution of 1280x1024

You didn't attach edid.dat to the post. You can run /opt/vc/bin/edidparser edid.dat to see all the modes possible.

You get no DMT modes because of hdmi_group=1 (which is CEA).

So, if you delete config.txt and boot what is the problem?
What mode would you like monitor to be in? 1280x720? 1280x1024?

From here:
http://elinux.org/RPi_config.txt

I would expect that
hdmi_group=2
hdmi_mode=35

would be a better fit, but I need to see the edid to be sure.

[TheFreeman04]

Sorry! /opt/vc/bin/edidparser edid.dat reports:
failed to open edid.dat
edid_parser exited with code -1
I've tried:
hdmi_group=2
hdmi_mode=35
No picture! 1280x1024 would be perfect!
