My graphic card is amd radeon hd 7470.Now I am trying Trisquel 7.0 in live mode and found that it has no amd radeon graphic driver.
Do anyone know how to install this driver?

The AMD/ATI (Radeon) cards all require proprietary software to work completely (3-D acceleration is always dependent on this proprietary software). This software is, of course, not included in Trisquel.

You can usually use these GPUs in unaccelerated 2-D mode, though. Is that the case for you, or is the display not working at all?

It didn,t display proper resolution.Correct display resolution is 1366*768 but now displayed at 1024*768.

That's what happens when using the Radeon driver without the proprietary firmware blobs doesn't work, if I'm not mistaken. It falls back to a generic driver that can only display up to that resolution.

Ideally, you should replace the Radeon GPU with one that is properly supported by libre software; Radeon GPUs are about the worst ones you can get. If your setup is an Intel CPU with a Radeon card, you can just pull the Radeon card out and use the Intel integrated GPU; this would be the best solution.

Otherwise, you'll have to get an Nvidia card that is supported by Nouveau. The best candidates are ones a couple years old, but this is just a general rule, so do some research. If you have a PCI Express slot, you can just get the GeForce card sold by Think Penguin, under "Accessories & Other Products":

If you use that link to get there, a portion of the profits will be donated to Trisquel.

Repeating my [comment in another thread][1] here:

I do have an Intel CPU, however I do not want to open up my laptop and physically remove the graphics card, but rather configure my system not to use it. How can I do this?

Would removing xserver-xorg-video-radeon do?

The NVIDIA graphics card won't work in a laptop. Laptops near-always use integrated chips. Either on the motherboard or in the CPU.

There is probably no good answer to this problem other than replace the laptop- or look more deeply into the graphics subsystem. There might be an answer somewhere on forcing via configuration the use of Intel graphics on the CPU if you have an Intel CPU with Intel graphics (most modern Intel CPUs do come with Intel graphics in the CPU so there very well could be a way to do this, but most people probably have never had a reason to do it, so there may be very little documentation on how to do it, though I haven't looked myself, recently anyway).
