onboard doesn't work correctly when i use two screens
hello !
first of all i want to say i am a beginner with linux and sorry i'm not very clever in english (i am french)
i should like to have help please for the following problem :
i want to use a very old pc to connect it with my panasonic tv
i have for that installed bodhi linux 3 on this pc and it works well
i have put onboard on the pc so that i can drive it from my sofa (the pc is just beside the tv)
when the pc is not connected to the tv, all is good with onboard :
the keyboard appears at the boot (i want this)
i have either the keyboard on the screen of the pc, or, when i click on the little cross of the keyboard (up on the right), the keyboard disappears from the screen and i have, instead of it, four little squares (black and white)
when i want the keyboard again, i click on the little squares and the keyboard appears again
so all is ok for me like that
but...
when the pc is connected to the tv (vga out on the pc and a converter to hdmi tv), the keyboard does not appear at the boot..
so i have to open it each time after the boot
and also, each time i click on the up right cross it disappears completely and it is not replaced by the 4 little squres black and white..
so i can't make the keyboard appear again...and i have to open one more time onboard to have the keyboard again on the screen
is there somebody who could help me please ?
i hope my english and so, my problem too, can be understood ?
No idea of your specific problem, and never used Bodhi 3. The only idea I have is to try adding onboard to your startup commands. I realize it already starts if you don't have your tv turned on, so not sure if running it again is a problem, if so you could just kill it first? I'm just guessing here. Assuming the program is called onboard, I'd add
killall onboard
onboard
to ~/.e/e/applications/startup/startupcommands (create if it doesn't exist).
thank you for your answer
i have allready added onboard on my startup commands and onboard appears when only one screen...
but...i think i have understood what happens when two screens, but not why...:
when i connect the pc to the tv, at the boot, i don't see onboard
but when i change monitor settings, there is on choice with which it appears, so i think onboard doesn't appear at the boot is because when there are two screens, the monitor setting of the pc is not the same as when not connected...
it is strange because at the boot with two screens, the images are not in the middle of the screen of the pc....and they are in the middle when not connected to tv
so the question is : why are the monitor settings of the pc different when it is alone and when it is with a second screen, the one of the tv ?
You answered yourself why the settings are different - one versus two screens.
Still doesn't explain why you're onboard program isn't starting. Are you 100% sure it's not running, maybe it's just on another screen or something like that.
Maybe put a delay in before starting it during boot to be sure both screens (when present) are fully initialized.
in fact i am quite sure that onboard is open at the boot, but i don't see it neithet on the pc neither on the tv
i think it is open outside of the screen, and that the reason why i can't see it
the problem is that the resolution of the screen of the pc is different when the pc is connected to tv ...and that, i do not understand why...
i understand that the resolution of tv can be different of the one of the pc, but i do not understand why the resolution of the pc changes when it is connected
so, when i connect the pc, i do not see onboard
i change then the resolution of both the pc and the tv, putting the same for the two, and then, all is ok , i have either onboard on the two screens, or, when i close it, i have the little icon (4 squares black and white)
the problem is that i have to change resolution each time i boot the pc when connected to the tv
what i look for is the reason why resolution of pc is different when alone or when connected to tv
the problem is that the resolution of the screen of the pc is different when the pc is connected to tv ...and that, i do not understand why...
can you run
Code:
xrandr
without your tv connected first and copy the first few lines of output? mine looks like this for just my laptop:
Quote:
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS-1 connected primary 1600x900+0+0 (normal left inverted right x axis y axis) 310mm x 174mm
and then run xrandr again with the tv connected to see if that part of the output changes? i don't have an external to compare that to personally. i just want to see if we can spot what might be different with yours
i go on
i just want to say i have found a solution to can see onboard at the boot when i connect pc with tv
in fact i have changed the place of the little icon black and white (4 squares) and put it on the left bottom corner and it works (probably it was hidden because o the change o resolution when connected to tv...)
however i will make what you told because there is always something strange with the screen resolution of the pc according it is or not connected...
but i have now a new problem with arandr and i will explain this on the other topic i opened before this one (pc does not remember screen resolution at the boot)
in fact the process creating a launcher seems not to work when i make it with two screens...but i have to try again because maybe i do something wrong...
i'll tell you later
back soon
i'm glad you were able to find a helpful solution to this problem and hopefully we can find one to the issue of your dual screen setup. if you have a moment to mark this thread as solved, that may help someone who comes across a similar issue in the future find an answer
