I am wondering if anyone else had this issue and fixed it:

I have been using Debian and Ubuntu distros for 3 years, and have had the same computer for all that time. It is a 2011 Asus CM6850-5 with an ¡5 chip, integrated Intel graphics, and 12 G of RAM. I never had any problem burning iso disks and installing from them until this 16.04 release. I like Xubuntu and Ubuntu MATE and was really looking forward to testing both before installing the LTS version of one of them to be my permanent OS for the next couple of years. Thing is, on both (and all other flavors and the main Ubuntu, too) the display is so blurry and distorted that installing is almost impossible, though I am familiar enough with the prompts to get through it. Upon booting into the new system the problem persists, although I am able in Xubuntu to get a readable display (1600x1200). My native display is 1920x1080 at 60 Hz, but I can't achieve that. It makes no sense to keep using the 15.10 versions because they will not be supported much longer, so I'm temporarily using Linux Mint 17.3 XFCE, though I don't care for Linux Mint.

Any similar issues or fixes?

Hi...

Looks like you're not the only one (although the OP was using Ubuntu in a VM.) You didn't mention what you did specifically to try and resolve this problem but does the information here help at all?

Also, if you would, please open a terminal and post the results of...

EDIT: I also found information here and here, if it helps.

I wonder if this issue will require another bug report...

Regards...

Thanks for taking notice -- I had previously seen the information you provide, though. I am using HDMI instead of VGA, but in any case those fixes do not help me at all. I think this is a problem with Ubuntu and/or the integrated Intel driver support in the kernel. I do not know how to bring it to the attention of those with Ubuntu who could fix it, though. Feel free to forward this conversation or link to it if you are aware of anyone who may be able to zero in on this. I miss Ubuntu very much, as it usually just works.

Here is the requested terminal information, but I'm now in Mint 17.3 XFCE while I work on the Ubuntu problem:

Hi...

You might want to file a bug report. Perhaps the folks there can help you with a solution. Apart from that, it's possible that the gentleman here might be able to tell you if it's possible to get in touch with a developer or how your issue can be addressed, although don't be surprised if he tells you essentially what I have.

Perhaps another member might have an idea on how to resolve this...

Regards...

Thanks. I went the bug report way through Launchpad under the title: Fatal Resolution Problem With All Ubuntu 16.04 Distros.

We'll see what happens. If I get any productive response I'll post it here.

Hi...

Could you post a link to your report. Thanks!

There is more information now in the above thread - my complaint resulted in the admission of a bug in the kernel the new Ubuntu 16.04 is using.

Hi...

Thank you, I hope this results in a solution for you and others affected by this.

Regards...

So, pursuant to answers.launchpad.net/ubuntu/+question/292402 there is a bug in the kernel Ubuntu 16.04 uses that affects my graphics driver. Questions: Couldn't I install an older kernel (sudo apt-get install linux-image-4.1.23-lts linux-headers-4.1.23-lts) and reboot to use 16.04? Would the "fix" be permanent?

Hi...

I'm not sure, I don't know if doing that might impact programs that need the current specific kernel. I guess you you could try it but keep the current kernel on hand in case you need to go back to it.

Regards...

Right. Not able to actually use 16.04 now due to the resolution issue, but was wondering because I wanted to find a way to do so. (Using Mint 17.3 now, but don't like Mint.) I posed the same question at Launchpad, but it appears no one will be answering. I can use 14.04.4 LTS, but everything is getting pretty stale there. If I don't do that Iḿ considering just using Debian (also stale) or maybe Sparky (based on testing, so a little fresher). Will miss Ubuntu, but a new computer is not in the cards right now.

You're welcome.

Hello, I have almost the same problem, and I kind of solved it following the instructions in:
garrypassarella's page: Add undetected resolutions in Ubuntu ...
(I can not post the link, because I'm new, but it was posted earlier by ardvark71 ... )

Even though the instructions were for older versions of Ubuntu, they kind of work for me.

So, I have my resolution back now (1600x900_60), but I have to set it every time I switch on my computer.

Moreover, in the "Displays" settings it says "unknown Displays"... but it works...

OK, viviz. Thanks.
