Any insights on what the problem might be and is anybody experiencing this also. Mine started a few days after I started using it.

If you move the task bar to the top of the screen does the problem move to the top or stay at the bottom? The flickering happens when, only at startup or randomly all the time? Only when the machine is warm or cold? I would run some stress tests and see if the problem happens at times of high CPU load, high disk access, during certain graphics, etc. What about plugged in versus running on battery? My guess is perhaps a power supply issue, or flaw in graphics hardware or screen (eg. borderline bad capacitor/resistor or something).

Thanks for your insights Brad. I switched my taskbar to the top of the screen and the flickering hasn’t happened since then, both at the top or at the lower part of the screen where it used to be. This is a pointer that it’s a software problem, and that is a relief. I also got a comment on the video on YouTube from someone that experienced same thing and according to him, it stopped after reinstalling windows.

Hello Norg,

So I checked out my screen to see if it had the same problem as yours and from what I can see, it doesn’t seem to have but I would rather you confirm yourself. Attached is my desktop with blue background. I hid all desktop icons and taskbar and then took screen shots with lightscreen. I also snapped with phone and attached both pics.

hmmm, the screen of jumper ezbook 3 pro is really proving to be a bummer. I will check out mine and report back what I find.

In the mean time, let me also update with my own screen flickering problem at the lower part of the screen. Have a look at a video capture of the problem here https://youtu.be/1Dd-x7bZCLs   and notice the flickering at the beginning of the video. Any insights on what the problem might be and is anybody experiencing this also. Mine started a few days after I started using it.

With regard to the screen, does it happen at a particular brightness level? Maybethe ribbon connector needs re-seating.

No I don’t think it happens at a particular brightness level, but I will be more observant now to see. Do you think I should continue watching this or get in touch with the seller on aliexpress. At this point, it’s still rare.

The trackpad needs to be adjusted in the settings, pointer options>motion, I set it at the 3rd mark or the 10, and reduced the number of lines it would scroll to 5 or less. I’ve got the microsoft driver from 2015. When scrolling a website, I have found that if you leave one finger on the touchpad and move only the other finger it works better, If i scroll up and down a website it often scrolls in the wrong direction then goes in the right direction. Maybe the metal hole surrounding your camera is a bit tight, will it just push down to make it flat? Mine looks flat.

I experience this too and my unit behaves exactly like this. The bezel area around my webcam is also a little pushed out like Alberto pointed out. I guess all those are minor issues.

However, I have one issue bothering me that I would also like to confirm with other buyers. About 3 – 4 days after receiving mine, I started noticing some occasional flicker at the lower part of my screen. The flicker is quite infrequent and it started with just a single row of pixels at the lower part of the screen. That row will just occasionally flicker to white. Even though its just a row f pixels, its quite obvious because of its contrast with the black task bar in windows 10. It think the problem might have increased to 2 rows of pixel or more now but I really cant say since its still rare and the flickering is quite fast. I really hope its not a problem with my panel as it would be such a deal breaker. Anybody experience it? Also, I’ll welcome insights on what the problem could be and what I can do. I really should make a video of this so you all can see.

Looking forward to your replies

Hi guys! I am UoF in LinuxQuestions and I was able to make Lubuntu 17.04 runnning on EZB3 PRO. I am using it atm. @brad: yes, I am good step by step follower, and I must admit, that I have learned a lot during my struggle to make it work. I picked Lubuntu, because it isn’t resources hungry. When the bare system starts to X, process manager shows 259 MB of RAM used. I would like to know, how much would that be with xubuntu or ubuntu/mate, so if anyone of you installs it, let us know, please. What works (out of the box):

• audio and video playback in HD from youtube (tested with this favourite song of mine https://www.youtube.com/watch?v=J8fFVOoqepc )
• bluetooth kinda – I was given a free bt mouse from Jumper (maybe like compensaton for long waiting for the batch with ssd extension slot) and after pairing and setting it is pointing device, it just works, although it isn’t good mouse, it has problem to work on white desk, where my other wireless mouse to usb has no problems at all), but I was unable to send photo from my phone (Xiaomi Redmi Note 3 Pro) to EZB via bt, but it pairs without problems. I made a test of wifi speed with this mouse connected and disconnected, and I didn’t experience speed drop as someone suggested.

What doesn’t work and needs further examination:

• touchpad – it doesn’t move cursor at all, instead it clicks (taps). I installed xinput and gpointing-device-settings (further g-p-s), and when I run g-p-s in terminal as root I get lots of X server errors – Bad Atom, bad Atom parameter in terminal. In gui of g-p-s and in xinput is my usb A4Tech mouse listed twice (don’t know why – maybe one id is reciever and the other is the mouse?) and CyPS/2 Cypress Trackpad. If I press Try button in g-p-s I get segmentation fault (it tries to allocate 80GB of ram, lol). It will need some command line tweaks for sure, but to me it doesn’t look like impossible, to make it work.
• functional keys for audio: fn +F1, fn+F2, fn+F3 – volume up, volume down work, mute works too, but as soon as you mute, you are unable to unmute with any of the keys and must do it with mouse in audio panel in taskbar – again i think it’s matter of settings.

I have not tested the camera yet. atm I am awaiting SSD and usb3 hub with 100GB LAN support, especially the SSD should be huge boost to performance <3 and I won’t be limited with 64 gb of disk space for dual boot. anyone feel free to ask, but please be patient with me, I still consider myself to be new to linux and moreover I am a family guy with 6month old daughter and I can’t fiddle with notebook all night long as when I was student. ;))

 

Can you kindly post a step by step guide on how you got linux  to work on your jumper ezbook3 pro? I am looking to install elementary os of kde neon on mine. Thanks
