Pixel C does not appear in device manager of PC



Hi.
When I connect Pixel C to PC, PC does not recognize it and it does not appear even in device manager. (Even "unknown device" doesn't appear)
And my Pixel C says weird message "USB supplying power to attached device", which I haven't never seen. I attached screenshots of that message.
And what is worse, charging Pixel C is also very unstable. Sometimes I can charge, but sometimes I can't charge.
Of course I can't use adb command. However, strangely, I can use fastboot command in bootloader.
I thought there was physical issue in USB type C terminal because even charging was unstable.
However, the fact that I can use fastboot command means there isn't always physical issue in USB terminal? I'm confused.
I tried several kinds of USB cable, but same result. A weeks ago, there wasn't any problem in my Pixel C.
Please help me! What is the problem?
Pixel C's USB terminal has broken? I don't want to believe, though.

Question about Dead Pixel!



I got my 1+3 yesterday and I have to say that this phone feels perfect just like the way 1+1 felt for the first time, I'm really happy with it :)
Back to my point, Day 1 Struggle 1 :P

Actually I've a little blue pixel just below the recents button of my softkey (see attached pic). I guess it's a dead pixel, kindly correct me if I'm wrong.
I purchased this phone from Amazon India and I don't know whether you people know or not that in India we have received a year of damage protection for free with this purchase but now due to this dead pixel I'll have to get my money refunded and then after the complete procedure of return I'll have to order another one as the terms of that additional warranty specifically says that I cannot refund/exchange the product once purchased.

My question now, is this dead pixel thingy contagious or something like that? I can manage with this single blue dot but I don't want to see my screen filling with more dead pixels after some time of usage.

If anyone can confirm this within few days then I won't apply for refund.
I hope I was clear with my question and if not please pardon me as my english is not really that good.

Just to make it more clear and precise, I am asking whether I'll have more dead pixels in future because I already have one on day 1 itself.

Hoping to hear from the experts soon :D

Dead camera pixel



Are these dead pixels? I have found 13 on my SGS7E

Can anything be done other than an RMA?

Thanks

Second Pixel C with same issue - backlight stops working.



I am on my second Pixel C where the backlight has stopped working after a month. The screen still works, if I shine a light at it just right I can see the contents (especially when they are white), but the backlight just doesn't come on. The previous one did this on and off for about a week while waiting for the replacement, meaning it would occasionally come back on and work for a little while. But, right before the replacement arrived, it went off and never came back on. My replacement did it for the first time today (it is one month old now), I connected to my laptop when I got home and issued an "adb reboot", and it appears to be working again. I have requested a refund from Google, but they said they couldn't authorize it, so I have filed a dispute with my credit card company in order to get my money back.

Overall, I like the device. I have had to work around a few of its shortcomings, but everything was satisfactory. I just can't keep replacing something every month.

Has anyone else experienced this? I mean, I know how to search and have found similar reports, this exact issue. Where the screen still comes on and is visible under the right lighting conditions, but the backlight is just non-functional. If so, what was the recourse you took to solve it? I have tried not putting it in my case (thinking that was the problem), rebooting (which occasionally has worked, but not always), factory resets (real tough without being able to see), plugging it in when malfunctioning, leaving adaptive brightness disabled, cursing at it and throwing my hands up in the air in frustration, etc. Nothing reliably works, and now I am afraid to let it go to sleep seeing how it came back after the reboot today.

Thanks for reading this...

Linux on Pixel C : Running ubuntu xenial in a LXC container



Hi guys,

Today i wanted to share with you some of my work to run linux on the pixel C. :D

First of all i'm not responsible for anything, so try this but i can't guarantee that it works for you and that you won't break your tablet (even though normally it should work ;) ).
Secondly this thread is for people who know how to use correctly adb, fastboot and linux console, instructions are not very detailed here, so if you're stuck try a bit to search, you will learn a lot !

So first what is LXC ?


LXC (Linux Containers) is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel. (wikipedia)

We are gonna use this technology to run ubuntu on Pixel C (we will even be able to access to the GPU drivers in the future, i'm currently working on it)

I developped all of this on DP4, so please update to the lastest android ! (I will give kernel for 6.X devices in the future).

So first, we need a special kernel where cgroups are activated.

Please download an flash my modified XCeed kernel on DP4 :
https://drive.google.com/open?id=0Bz...mQzeUZTYmlGWFE


Code:


fastboot flash boot boot.img

Try to see if you can run su in the tablet, otherwise you will have to install supersu.

Now, install busybox so that we have some tools to help us a bit : https://play.google.com/store/apps/d....busybox&hl=fr :)

Download now lxc compiled with PIE support for Pixel C and the ubuntu rootfs (here is a 32bit version, 64bit is also working fine on my tablet :) ) :
https://drive.google.com/open?id=0Bz...nJBbS1LbGo0MUE

send it to the pixel C :

Code:


adb push lxc.tar.gz /sdcard/

Now extract the archive in /data

Code:


adb shell
su
tar xvzf /sdcard/lxc2.tar.gz -C /data/


Now run ubuntu and enjoy ! :highfive:

Code:


# open a terminal as root on the tablet
# execute :
/data/lxc/startSystem


If everything goes well, you will see ubuntu booting ;)

Internet will work out of box if your tablet has a net access, you can install, remove things using apt :)

What is going on for this project :

I'm currently trying to use the GPU drivers using libhybris so that in the future we can run wayland on pixel C and have a fully working linux environnement ! (KDE, gnome)
see here for KDE, we need to port this : http://blog.bshah.in/2016/05/02/plas...w-base-system/
I need help for this (because it's difficult). For this, we will have to patch bionic so that we can use libhybris. All the devs can contribute here :))

If you're happy of this work and you want to have more detailed instructions please pay me a beer ! Because developing for Pixel C is time consuming ;)
