Did you save the arandr screen config? If so, then open a TTY (Ctrl-F1) and edit it or delete it (probably in ~/.screenlayout)

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

As far as I remember I choose resolution I and clicked apply - nothing more

I will try it tommorow.

Do You have any ideas how to get at least 1024x768 resolution?

I described how to access the settings by opening a TTY. You can create a new screenlayout script with:

mkdir -p ~/.screenlayout
nano ~/.screenlayout/layout.sh

Add this to the layout script (assuming you are using VGA-0):

#!/bin/sh
xrandr --output VGA-0 --mode 1024x768 --pos 0x0 --rotate normal

Use Ctrl-o to save, Ctrl-x to exit the editor

Then restart.

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

Hello

Today I'm able to logon but still have 640*480 screen resolution and I can't open TTY using Ctrl+F1

I started to play with:
Preferences>Display>ARandr Screen Layout Editor > Output I see:
LVDS - active - resolution 640*480
DVI-0 - active - couple resolution to choose, and 640*480 enabled
When I change it to i.e. 1280*1024 and commit it, my screen went black.

How to fix my problem?

Regards
Slawek

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

Sorry, nobody spotted that I should have said "Control-Alt-F1"  :8

256MB of memory is the minimum requirement, but perhaps it isn't enough for your graphical setup? Maybe it can't run 2 monitors.

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

I tryed Ctrl-Alt-F1 ... something strange is going on
When I pressed it black screen appear and I dont know how to go back to graphic console.
Is looks like the same as when I try change resolution using arandr.

This computer has 1GB DDR2 so this isn't such problem. Also has only DVI as a monitor output. Any other ideas?

Is it possible to use from the link above:

lts.conf

    #thinClients Futro S450 list of all macs
    [aa:19:99:6a:xx:xx]
    LIKE=FUTRO
    #thinClients Futro configuration in general
    [FUTRO]
    CONFIGURE_X=False
    XRANDR_MODE_0
    X_CONF=/etc/X11/xorgFutro.conf

Regards
Slawek

C-A-F1(to F6) should give you a TTY commandline

Return to the graphical screen with C-A-F7

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

If I switch to TTY using C-A-F1 - I _can't_ got back. I need to power off and start over.

Do You have any ideas what I can try?

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

Hello

I did dist-upgrade - but without any changes in my problem.

I discovered that I can set 800*600 resolution, small change but usefull.

SO I try to do what You tell me, I created and edited layout.sh

#!/bin/sh
xrandr --output LVDS --off --output DVI-0 --mode 800x600 --pos 0x0 --rotate normal

Unfortunetelly after restart I had LVDS active and 640*480

I spent some time on googling and I found solution to disable the LVDS display at boot.https://ubuntuforums.org/showthread.php?t=2164669
but where I sould edit

append ro initrd=initrd.img-3.8.0-26-generic init=/sbin/init-ltsp quiet splash plymouth:force-splash vt.handoff=7 root=/dev/nbd0 video=LVDS-1:d

Where (how to locate this file) I should change settings?

I need to remove LVDS (by unclik active) and next I'm able to use even 1680*1050 !!!

So question is - how to permanently remove LVDS and force using layout.sh

Don't do that!!! It is a kernel command when you boot an Ubuntu system.

In this Debian post it suggests you add

"video=LVDS-1:d" to the linux boot line in grub.cfg (just before "root=…")

Instead, I suggest you try it first before making it permanent. When the grub screen appears during the boot process, press "e" to edit the boot parameters, and add "video=LVDS-1:d" to the end of the line which starts with "linux".

If it works then make it permanent by editing (as root) "/boot/grub/grub.cfg", and add the kernel parameter to the "menuentry 'BunsenLabs....'" section

Well done smile

See my post above for a possible way to disable LVDS.

You can force layout.sh by adding it to your Openbox autostart (make sure it is executable)

~/.screenlayout/layout.sh &

Re: [SOLVED] Fujitsu FUTRO S450 resolution problem

Hello

My issue was definitelly connected with two outputs. I don't know what is LVDS but when it's diabled everything working as expected.

I did changes in grub.cfg only.

Thank You again
With regards
