Acer C7 (710) no video in V72 Special Build

Open zerbey opened this issue 6 years ago • 6 comments

Was previously working fine in V69 Special Builds. Booted from USB V72 Special and it does boot (I hear the sound), but no display.

Uses the following GPU I believe - GMA5700MHD

Give https://chromium.arnoldthebat.co.uk/.testing//chromiumos_image.bin.gz a test please. Expect lots not to work, but hopefully the video will spring into life.

No joy, still no video on this build.

Tried opening up a terminal window too and no go. I'm happy to help with other debug builds just let me know.

On Acer CB C720P I just tested https://chromium.arnoldthebat.co.uk/.testing//chromiumos_image.bin.gz which is an alpha release of R73 - no dice, it gets even worse it returns to the white screen - neither ctrl-U nor ctrl-L works... It does boot & works with caveats on other x86 laptops such as Acer Iconia W700 & Chromebook Air mid 2011, one of the caveats is webcam not working with error File System error... R69 is the last one that works for Acer CB C720P... RFC why didn't you compile R71? can you point me to instructions on how to compile an image, I'd like to learn how to do it, & see if I can solve issues for myself :)
