Re: (solved) resolution change with hdmi connection

What is your graphics hardware and drivers?

lspci -knn|grep -iA2 'vga\|3d'

Can you set the correct resolution for your HDMI display using

arandr

Hello,

graphics hardware and drivers:

jjr@debian:~$ lspci -knn|grep -iA2 'vga\|3d'
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09)
	Subsystem: Toshiba America Info Systems Device [1179:0011]
	Kernel driver in use: i915

With "arandr" :

Hdmi no connected :

Vue -->  1:8
Ecrans--> LVDS1 Active . Résolution : 1366x768  . Orientation normal

Hdmi connected

Vue --> 1:8
Ecrans --> LVDS1 Active . Résolution :640X480  . Orientation normal
           HDMI1 Active . Résolution :640x480  . Orientation normal

I have tried to modify resolution LVDS1 and HDMI1 without success

I am working in dualboot and it's correct with W7.

Thanks for your help

Realy , before  2 updates it was perfect one month ago.

Veuillez expliquer - en Francais - plus en detail ce qui se passe. Quand vous connectez la TV vous voulez une copie de LVDS1 sur la télé ou autre chose?

Re: (solved) resolution change with hdmi connection

Oui,
Je souhaite voir l'écran du pc sur l'écran tv.
Avec la commande:

xrandr --output HDMI1 --mode 1920x1080i

Je vois l'écran du pc en 6 exemplaires sur l'écran tv et le conky se trouve en plein milieu.
J'ai essayé de modifier les résolutions sans succès.
Dès que je branche le cable et que je mets en route le pc , la résolution de l'écran pc est modifiée.
(Si le pc est en marche et la tv également et si on connecte le cable : rien sur la tv . Il faut d'abord tout brancher mettre la tv sur ON puis le pc sur sur ON )
Il y a un mois environ tout fonctionnait parfaitement.
Merci

Re: (solved) resolution change with hdmi connection

Is there perhaps a function key on the laptop that allows you to switch between different resolutions and/or  output devices.
I have Fn + F8, yours may differ.

or

Is there a possibility to cycle through resolutions (modes - aspect setting) on the TV side?

or

You may have to switch off PC screen to get correct resolution on the TV:

xrandr --output LVDS1 --off --output HDMI1 --mode 1920x1080i

Re: (solved) resolution change with hdmi connection

Hello,

You can see the following picture (screen TV) when I connect HDMI cable :

To solve my problem :

1. In terminal:

xrandr --output LVDS1 --off --output HDMI1 --mode 1920x720

2. Restart wallpaper in préferences with apply.
3. Restart conky

And I have the screen perfect on the tv:

I suppose problem of time to start different sw : wallpaper , conky .....
and also why at the beginning, the résolution is automaticly 640x480.

Neverless I can see on the tv. I will check with my old crunchbang if the problem appear.

xaos52: big thanks for your help.

Re: (solved) resolution change with hdmi connection

Hello,

In fact , same pb with crunchbang warldorf.

Better to  switch off PC screen and after adjust resolution Tv screen with arandr or xrandr.

I suppose timing pb during starting system.

I note "solved".
