If the workaround doesn't work, we are sorry that Tails does not work well
on this computer. Our best hope is that a future update of Linux drivers will
solve the problem.

Other graphics cards in the [[!wikipedia Radeon_RX_400_series]] might be affected.

Graphics cards in the [[!wikipedia Radeon_RX_Vega_series]], as found in some AMD Ryzen processors, might be affected.

i915.force_probe=MODEL

… replacing *MODEL* with the 4 characters you see after `8086:` on the error message.

For example, if you see an error about `8086:4c8a`, use this boot option: `i915.force_probe=4c8a`.

For example, in the Dell Latitude 7490.

<h2 id="multiple">Multiple graphics cards</h2>

If the error message lists multiple graphics cards:

If possible, plug in the monitor into the motherboard's Intel graphics card, as opposed to the external Nvidia or AMD/ATI graphics card.

Explicitly select one of the two graphics adapters in the BIOS instead of letting the system choose one automatically. If this does not solve the problem, try selecting the other graphics adapter.

For example, in the Acer Aspire e13.

<h1 id="other-issues">Other issues</h1>

Some computers with switchable graphics (such as Optimus) fail to choose a video card and end up on a black screen. This has been reported for MacBook Pro 6,2, MacBook Pro 10,1 Retina, MacBook Pro 15-inch (early 2011) and might affect many others.

For the Mac computers, it is possible to use a third-party application, <http://gfx.io/>, to force integrated graphics only through macOS. Then restart in that special mode that works with Tails.
