I already thought about offering a package of the driver on my blog, but sadly even with some online tutorials I wasn't able to create a working package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1123943 Title: Chrontel CH7036 chip not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1123943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@carli I guess it is easier and more useful to push for a change from Debian side, since multiple desk distros depend on Debian. Maybe close this one and re-file it in Debian?

Did any one try to make this work on Ubuntu 14.04? On a different issue, does anyone know of a driver for Broadcom Crystal HD 1080p?

[Bug 1123943] Re: Chrontel CH7036 chip not supported
Yeah there are many tablets like this. They are alll based on the Pegatron Lucid and sold under the name ExoPC, WeTab, Ciara Vibe, JS-Tab, W8Pad etc. Most come with Windows 7 but the WeTab came with its own Meego-based OS which had drivers for everything in the tablet. Did you try some configuration options in /etc/chrontel-wetab.conf? You could try the -Enumber 1-6-parameter for forcing some test edid numbers. Maybe with that the driver ignores the missing signal. If that doesn't work you can force one of the following resolutions 0 - HDMI 640x480 1 - HDMI 720x480 2 - HDMI 1280x720 3 - HDMI 1920x1080 4 - HDMI 1920x1080 5 - HDMI 720x576 6 - HDMI 1280x720 7 - HDMI 1920x1080 8 - HDMI 1920x1080 9 - DVI 640x480 10 - DVI 720x480 11 - DVI 720x576 12 - DVI 800x600 13 - DVI 1024x768 14 - DVI 1280x720 15 - DVI 1280x1024 16 - DVI 1440x900 17 - DVI 1680x1050 18 - DVI 1920x1080 19 - DVI 1600x1200 20 - DVI 1600x1200 21 - DVI 1600x1200 22 - DVI 1920x1200 with -Mmodenumber.

[Bug 1123943] Re: Chrontel CH7036 chip not supported
If I had HDMI turned off to start with, your method would not turn it on. There was no error message in the complete process following your instruction, but HDMI display shows 'no signal'. $ sudo /usr/sbin/ch7036_start /usr/sbin/ch7036_monitor: starts Found device ID 0x56 Found revision ID 0x81 Mode 1024x768 (95) 1024x768, dot clock 6500 -Hsync -Vsync H: start 1048, end 1184, skew 0, total 1344 V: start 771, end 777, total 806 Firmware size = 3295 bytes. As said, the device works on Windows 7. I down-tuned the resolution, because even on Windows 7, the max resolution offered for HDMI is 1280x720, smaller than LVDS's native resolution and CH7036's advertised max resolution (both are 1366x768). As you can see the resolution is 1024x768, that means in Linux I down- tuned it even lower than Windows 7, because in xrandr, the next resolution below 1366x768 is 1024x768. I was rather surprised when I look up the specs of WeTab and found that bModo has exactly the same configuration, including CPU type, memory, hard disk space and resolution. It really look like bModo 12 is just another casing of WeTab. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1123943 Title: Chrontel CH7036 chip not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1123943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

A few days ago there was a post of a different workaround: Installing the Chrontel Ch7036/HDMI - Output on Ubuntu http://lackofalucidmind-en.blogspot.de/2014/01/hdmi-output.html I tried following the instruction myself and to my surprise once the executable is launched (/usr/sbin/ch7036_start) it turns off my HDMI which was originally on (I had rebooted to Windows and had turned it on, and rebooted to Linux while it is still on). Perhaps that's because I am not using a chrome book.

[Bug 1123943] Re: Chrontel CH7036 chip not supported
We generally ask bug reporters to first request that the driver be added to the upstream kernel. This can be done by mailing the Linux Kernel Mailing List or opening a bug at bugzilla.kernel.org. People affected by this bug are probably wondering why the kernel team doesn't just add the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch/driver to a kernel that is not from upstream. Applying patches and adding drivers that don't come from upstream add greatly to the support of the kernel as other upstream patches/drivers may touch the same area as the non- upstream patch and may prevent them from applying cleanly. ** Changed in: linux (Ubuntu) Importance: Undecided = Medium ** Changed in: linux (Ubuntu) Importance: Medium = Wishlist ** Changed in: linux (Ubuntu) Status: Confirmed = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1123943 Title: Chrontel CH7036 chip not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1123943/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
