Monitor Resolution

Postby Swabbie » Thu Aug 07, 2014 6:17 pm

I recently got a new Windows 8.1 laptop (a HP Pavilion 17-f053us) and wanted to use Ubuntu as I do on all my other computers. I was going to dual boot with Ubuntu 14.04. I started running it as a live session booting from a DVD and when I did the screen resolution defaulted to 800x600 and gave no other choices and did nothing when I tried to have it detect the monitor. I considered that it could be a problem detecting the video card but could find no evidence of it. I then thought I would go ahead and install as dual boot and then update and see if it fixed the issue. Then I had no option to install alongside Windows 8.1. I decided to go ahead and take the plunge since I had made the restore DVD's and it was a new system. It installed flawlessly with full disk encryption and an encrypted home directory but still the monitor resolution problem. Updates did nothing. I researched the issue and ended up in a maze that had no solutions. I did shut off fast boot in Windows 8.1 before I tried this. So I just restored the computer to Windows 8.1 with the disks. I so do want to run Linux and prefer Ubuntu but so far this only works as a Windows machine with the resolution issue. Any thoughts?

Ah, a laptop from HP.
First check the resolution Windows is using, then check the graphics chipset being used.
It may be an issue with lack of adequate drivers for the graphics.

And that will help me find the proper drivers in Linux?

It might help.
Once done, you can
a) google for problems for that type
b) google for linux drivers
c) search the ubuntu forums for the appropriate help

It might be a setup problem, drivers, or just a lack of support for your particular hardware

How can knowing the chipset not help with finding drivers?

You can also find this info in Linux with lspci. Add the -k option to see the driver currently in use. Once you know what it is using and what it should be using, you can solve the problem.

I am having a similar problem with my 64 bit Ubuntu Studio 14.4.1 installation on my laptop. It will only give 1o24 x 768 on my external vga monitor whereas Windows 7 gives 1280 x 1o24. I've got ATI Mobility Radeon HD 4250 graphics. How do I install the propriety drivers? tia, aha from Alex.

click on the lens, type "drivers".
you should see an icon for additional drivers.
click it, it will search for the drivers.
Once finished, you should see the driver in use and any alternatives.
with AMD, you will see fgrlx, with Nvidia, you will see nvidia.

This also works for some other hardware that requires proprietary firmware (TV cards etc)

I looked up and it says that the hardware is supported and it also says it is in the certified systems for the HP Pavilion 15 and I have the 17 which could be part of the problem.

You are using the radeon open source driver. The proprietary drivers often give more features/performance. According to http://support.amd.com/en-us/download you need the Catalyst driver, which can be downloaded from there if it in not in your package manager.

The Catalyst (fglrx) drivers also give you smoother hi-res video.

Serious Question

Postby Swabbie » Tue Aug 19, 2014 6:32 pm

Not knowing how to do many of these things being a new convert to Linux this was a serious question.

But you need to know the make of graphics card to install the right drivers in Windows as well.
While a lot of hardware "just works" these days in Windows and Linux, graphics cards usually need proprietary drivers supplied by the manufacturer to get the best results.
(They may have been pre-installed by HP on your laptop)

Either way, without knowing what graphics card is in your laptop, there is not much more we can do to help you.

The instructions I gave will work with Ubuntu 14.04 (the lens is the round thing in the top left hand corner). They should help you install Nvidia or AMD drivers.

Edit: just searched on HP.com, your laptop has the AMD Radeon chipset.

I do not know if this was meant for me as I did not see you quote any part but assumed it was not since it followed Alex01UK and I thought it was in response to his posting.

As for mine I researched and I have AMD A-8 6410 APU with AMD Radeon R5 and as I indicated in an earlier post it is supported in the 15 model of this laptop but no mention of the 17. And to reiterate I still have no option to install alongside so I cannot dual boot although that might be a topic for a different post. So far what I have found is that I may have to manually do things to get it to dual boot and then possibly install the update I found for drivers and that will fix the resolution problem. I wanted to find a solution to the resolution issue before I set things up to dual boot.

Actually, it was meant to be in response to both, as it works for both.
Installing the additional drivers also installs the AMD Catalyst control centre which works in a very similar way on Linux and Windows.

The dual boot problem is probably a Windows 8.1 issue, as previous versions of windows are easier to dual boot with.

Actually knowing the graphics card may be a big part of the problem as when I go to look for additional drivers it says that the card is not identified.
