-# Fix "No frame buffer" error in Plan 9
-
-Let's say you installed [Plan 9 by Bell Labs](https://en.wikipedia.org/wiki/Plan_9_from_Bell_Labs) on a QEMU/KVM virtual machine by just following the prompts and entering defaults. In certain cases, you might find your install booting to a shell with the errors:
-
-```
-aux/vga: inportl(0xc100): permission denied
-rio: can't open display: initdisplay: /dev/draw/new: no frame buffer
-init: rc exit status: rio 31: display open
-```
-

-
-For some reason, on certain configurations, the `xga` (`vga`) monitor type does not work when booting into Plan 9, even though it works fine during install. The fix is to adjust monitor settings to `vesa`:
-
-1. In the shell prompt enter
-
- ```
- aux/vga -m vesa -l
- ```
-
- You should get a cursor and a cleared prompt.

-
-2. In this "new" shell prompt, enter
-
- ```
- rio
- ```
-
- You should now get a grey background with the cursor in it.
-
- ![](./img/manual-rio.png)
-
- - You are now in a graphical environment, so technically you can stop here. The other steps are for configuring it so you wont ever have that problem again.
-
-3. Create a new window (refer to the bullet point for instructions). Enter
-
- ```
- 9fat:
- ```
-
- and afterwards
-
- ```
- sam /n/9fat/plan9.ini
- ```
-
- this is the configuration file we will be changing.
-
- ![](./img/rio-9fat-commands.png)
-
- - How to make a window: right click, hold, hover over "New" and release the right click. Now right click somewhere in the top left, hold, drag to somewhere in bottom right, release.
-
-4. Now we will be editing the config file with sam, a line editor. Click the green-backgrounded box, the cursor should appear.
- First select our file:
-
- ```
- b /n/9fat/plan9.ini
- ```
-
- and click the green-backgrounded box.
- Then replace `xga` with `vesa`:
-
- ```
- , x/xga/ s/xga/vesa
- ```
-
- and click the green-backgrounded box again. We're almost done here, enter `w`, wait a bit, and finally enter `q`.
-
- - If you want to check whether the file was properly saved, feel free to run
-
- ```
- cat /n/9fat/plan9.ini
- ```
-
- and check that monitor is equal to vesa (you can scroll with the arrow keys, or with left and right mouse buttons, acting as up and down).
-
- ![](./img/rio-plan9ini-cat.png)
-
- - The first command opens the `plan9.ini` file for editing, and the second command, finds every line that contains `xga` (there should probably be only one) and on each matching line replaces `xga` with `vesa`. Refer to the [docs](https://p9f.org/sys/doc/sam/sam.html) for more information.
-
-5. That's it, all we have to do is halt our file system with `fshalt` (or type out the command in the [Qemu installation guide](https://9p.io/wiki/plan9/Installing_Plan_9_on_Qemu/)) and Force Reset the virtual machine.
-
-The next time you boot into Plan 9 and into your user, the graphical environment should load fine. Enjoy Plan 9!
