I followed instruction on plugable.com/category/platform/linux/ and successfull connected my monitor to USB port using plugable usb 2.0. But I have one problem. I have very low-end computer(800MHz mipsel processor) and my monitor on its highest resolution(1920x1200) works extremly slow. So, first question: can I speed up refreshing or if not how can I change resolution of my screen(I belive lower resolution could speed up refresh time). I’m using Debian Wheezy.
Hi Szymon,
Thanks for posting your question! I’ll be happy to help. There’s a couple of things you can do to try and improve the performance of USB graphics on your system. One tweak that may provide a bit of a performance boost is to use the DisplayLink X server and disable fb_defio in the module options.
First you’ll want to build the displaylink X server by following step 2 at the following link:
http://plugable.com/2009/11/16/settin…
Then be sure that you have the driver line correct in step 5 of the above link. It should contain the entry “displaylink” for the line “driver” in the “device” section.
Once that’s done, reboot. Then,
At the following link:
http://plugable.com/category/platform…
You’ll want to set options udlfb fb_defio=0
Now, reboot again. To lower your screen resolution you’ll need to configure X to use a lower setting, there’s usually a way to do it through your window manager, like gnome control center in gnome. Here’s a couple of links with good information regarding getting X set up.

I hope this helps.
Let me know how it goes,

Backtrace:
When I start my Xserver my netbook screen becomes black but my monitor stays green. So I cannot see anything. Do you know what is wrong?
Hi Szymon,
Thanks for the additional detail. The server section in your Xorg.conf won’t be needed for a single seat setup. Although I don’t see errors relating to these entries in your Xorg.0.log, let’s try commenting out the following lines and see if it works.
Section “ServerFlags”
Option “AutoEnableDevices” “false”
Option “AutoAddDevices” “false”
Option “DefaultLayout” “seat”
Option “DontZoom” “true”
Option “DontZap” “true”
Option “AllowMouseOpenFail” “yes”
EndSection
Let me know how it goes,

No, it doesn’t help. Do you have any other possible solutions? And can you tell me which Linux distros or Xserver versions the displaylink driver was tested for?
Hi Szymon,
Sorry to hear that you aren’t having better luck with the DisplayLink X server. Did you get the display to work with udlfb fb_defio=0 and the DisplayLink X server? Or did you still have the black screen? If you did get it working, then the next step to try is lowering the resolution but after that, you may be up against the limitations of the hardware.
Let me know how it goes,
Jerome.
Hi Szymon,
Here, we’ve tested mostly on Ubuntu, SuSE, and RedHat setups on x86 CPUs.
Once the udlfb is working with fb_defio (per these instructions http://plugable.com/2011/12/23/usb-gr…), as it was on your 800Mhz 1920x1200 setup, then is should be a short hop to switch over to the more optimal damage-based notifications:
- Make sure you have the ‘displaylink’ X server, which it seems like you do.
- Switch driver “fbdev” to driver “displaylink” in xorg.conf to use that driver
At that point, initial writes to the framebuffer will trigger page faults (to detect changed regions), but as soon as the first damage ioctl comes down, udlfb will switch to mostly relying on the damage reports (which is far more optimal than page faults).
- After 1 & 2 work, further optimize by turning fb_defio option off in udlfb, so udlfb relies only on the damage notifications.
But is seems like something is going awry getting there.
Quick question: In the /var/log/Xorg.0.log that was posted earlier, it looked like some good information (a backtrace, possibly from a problem) was just below the section you pasted. Was anything else in the /var/log/Xorg.0.log file below that? And could you post the /var/log/kern.log udlfb output from the same period of time?
Thanks - what you’re trying to do is common, so the solution will be a help to others!

I posted whole my /var/log/Xorg.0.log file. I have one more observation. When I use displaylink driver and start X it completly block my computer. I cannot press Ctyl+Alt+F(1-7) to return to tty. When I set fb_defio=0 my monitor doesn’t work even with fbdev driver. Below I posted a result of ‘cat /var/log/kern.log | grep udlfb’ command:

When I trying to turn xserver on. It starts successfull but screen is divided into three parts(each of parts looks as the extra monitor connected with “–same-as” xrandr option) and striped all over. I can run applications normally but it is impossible to work.
