    Default Problems connectin PC to TV

    Hi
    I am running Leap15.4/KDE standard install. I tried to connect the old Asus laptop to an older TV using an HDMI cable. On the console the xrandr command shows that the TV is recognized:
    Code:
    xrandr 
    Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192

    DP1 disconnected (normal left inverted right x axis y axis)
    
    Systemsettings5 even recognizes that the TV is from Philips and says Philips Consumer Electronics Company in the Devices Field (where I can switch between laptop screen and this TV screen. FUrther down I have set this to Replica of Laptop Screen. On the TV the settings are HTMI1 and source PC. But the TV screen stays black. Any ideas anyone how I can get the TV to display what is on the PC screen?

    Try a different HDMI cable

    Please run inxi -U using superuser authority, then provide Konsole input/output from:
    Code:
    inxi -GSay
    I'm guessing simply removing the xf86-video-intel and xf86-video-all packages may fix this. Show inxi -GSay both before and after the removal if the package removals failed to fix this.

    You see I have the xf86-video-intel..... and a lot of other xf86-video.... packages. I have Intel graphics card (as you see the nouveau driver which was part of an update). Which ones do you think should be removed?

    It's not important, but the only ones I would keep are vesa and fbdev as fallbacks to be used if and when something goes wrong with a future kernel update that breaks normal Intel X graphics support.

    Hi mrmazda
    I was busy yesterday evening so I continue this morning. I deleted the following packages: xf86-video-intel as you wrote in your previous email, xf86-video-vmware since I don't have a virtual machine on this computer, xf86-video-nouveau since I don't have a nvidia card and xf86-video-voodoo at random. Afterwards the computer only booted into command line (what was used to be called runlevel 3). So I reinstalled xf86-video-intel and now the computer boots again into the GUI. the command inxi -GSay now is exactly the same as previously and TV still shows nothing. One further thing - as soon as I plug the HDMI cable into the laptop and the TV is recognized (command line and Systemsettings5) the panel on the screen disappears. With a right click on the screen I have to select + Add Panel -> Default Panel to get it back. I will try around deleting other xf86-video drivers (except intel, vesa and fbdev) and see if anything changes. If so I will write here again.

    I have now deleted all xf86 packages except the following:

    As you can see the command inxi -GSay shows the same as before and the situation has not changed. THe TV doesn't show anything but a blue screen. Any further ideas?

    Hi
    I would check the TV menu system for configuration options there....

    Thanks malcolmlewis, the TV settings are OK. I tried this TV with my Tumbleweed computer (which I carried upstairs) and there the HDMI connection with the same cable to this TV works without any problem. THe problem consequently must be on my laptop here.

    What does
    Code:
    grep -Ei 'intel|odese' /etc/X11/xorg.conf.d/*conf | grep -v tifier
    report? If Driver "intel" shows up, back it up (in place but with another name not ending in .conf, e.g. .conf1), then try changing intel to modesetting and restart. If it doesn't help, add a new line following the one you changed containing:
    Code:
    Option  "AccelMethod"   "exa"
    and try again. If still no help, try again replacing exa to none and try another restart.

    If Driver "intel" doesn't show up, create a new file /etc/X11/xorg.conf.d/07-intel.conf containing:
    Code:
    Section "Device"
    	Identifier	"IntelKludge"
    	Driver		"modesetting"
    EndSection
    Then restart X.


    I have another idea involving xrandr that I will save for if none of the above solves.
