Screen laptop producing distorted images

Question

My Acer Aspire 5250 is running linux mint 17, I usually use it with a stand alone monitor because its screen is cracked. Yesterday the screen started to distort as shown in the screenshot. https://www.dropbox.com/s/u7hslep0zdmgz7b/yt3LlYX.jpg?dl=0 I have tried to change resolutions it didnt work. I have tested the monitor with another machine and its working perfectly. When using vlc, videos play without distortion but all other applications are affected by the distortions. What could be causing the screen distortions?

Comments

lines and distortions on screen are caused by bad ram.
if you have 2 ram chips, pull out one and see if you get a change, then pull out the other one to see if that helps.  you dont get driver problems for base hardware with the linux kernel.

How do explain this??

Thank you. I have removed the chips, interchanged them, put them one at a time and there has been no change..then I ran memtest and it says the ram chips are okay.

---

did you try to get ram chips from elsewhere? because if that doesnt help then its worse. its the gfx chip. u cant change those on low end and mid end lappys.  an OS change wil just flush your cache but the problem wil return. hardware is failing somewhr in thr. my worst case advice, get ready to invest in a new laptop.

This laptop was just for downloads, I guess its time to retire it now.

the law of laptops, when something breaks you buy a new one. if its just for downloads, maybe buy a biggish tablet? better lifespan and easier maintenance plus no ram line on screen unless you drop it?  u can even get Office, a separate keyboard and better mobility.

Answer 1

This looks like a graphic driver. Try to change your driver from open driver to propietory one or vise vesa. Is your monitor cable still hold firm on the laptop? Is it a serial connection or hdmi, try to swap between the 2 if your laptop support it.

I notice you ar using 17.1 and the latest is 17.3. Try to update your system then upgrade it. Its a breeze in Linux Mint and l have yet to loose any data although a backup of all your important data is recommended.

Reason why lm asking you to upgrade is that every new linux OS comes with better graphic support which might help your problem.

its Torvalds. with an L.

you've neva writen a single line of code. u r un-initiated. a muggle.

this forum is now off topic. as admin i am closing it.

Did l ever claim to have wrote a code? Do you think anybody who is in IT needs to have writen a code to be initiated! I specifically chose not to be a programmer for the same reasons and traits you are showing here. Programmers suck big time. Wether its capital letter L or whatever doesnt matter, are you his biographer now??

Why do you want to close this now, you are trying bullying tactics? You are trying hard to imitate Torvalds bcoz bullying and arrogance is what he is well known for!! Unfortunately you cannot match his achievements.

Ooops! Did you jus said you closed this

You are more than welcome to ban me not only from this forum, but from internet!!

If you closed the post then no one should be able to reply or post after. So how come lm stil able to reply? Is it because maybe your bullying tactics are failing.

Maybe my ignorance is beating your bullying ;)
