No Video through HDMI after Upgrade

Running Libreelec on a Lenovo N22 Netbook with Philips TV attached via HDMI. Worked fine on LE 10.04 but after upgrade to 11.06 I'm not getting video on the TV. Libreelec splash screen displays on both TV and netbook, but as soon as Kodi GUI starts I get no video on the TV. Audio works, just no video.

Trying getedid create as was mentioned in threads with similar problems, but I get stuck at find . -print | cpio -ov -H newc > ../edid.cpio when the system complains the file system is read only.

Stumped.

You can force the older intel i965 drivers by creating /storage/.config/kodi.conf:

Now it just gets stuck at the Libreelec splash screen.

See if adding "video=HDMI-A-1:1280x720M@60" to boot params helps?

Boot params? Where? On raspberry pi it's in the config.txt file, but I'm not running a pi.

Code

mount -o remount,rw /flash
nano /flash/syslinux.cfg

^ edit and add params there

Thanks for trying to help, but that didn't fix it either. I also tried adding "video=HDMI-A-1:1360x768M@60" and then tried "video=HDMI-A-1:1366x768M@60" to boot parameters as well, but that made no difference.

Count me in as one of those "blabbing on" about that "weird resolution" lol. I'll agree it's weird, but my HTPC and my Pi ran on that same TV at that resolution for over 10 years just fine. It's also the only resolution available on the Lenovo N22 and I suspect that might be part of the reason I had problems with upgrading through Libreelec.

I went ahead and downloaded legacy generic 11.06, did a clean install and restored a backup from 2 weeks ago. Works fine now at 1360x768, just like it did before I tried to update. I don't remember if my original install was from a standard or generic package, but I'll remember to download the generic to upgrade in the future. Thanks again for trying to help.

I suggested "video=HDMI-A-1:1280x720M@60" and not "video=HDMI-A-1:1360x768M@60" for a reason

Yep, and when your suggestion didn't work I figured I'd take a shot in the dark and meddle around and try a few other things before giving up and doing a clean install. My time wasted might save someone else a few minutes of their time.

You're probably right in that Linux doesn't like that 'weird resolution', but it does work. Though at least in my case, it only seems to work from a clean install.

In any event, I'm up and running and again and appreciate you trying help salvage my messed up system.
