I own an Acer aspire 4736z and I had some problems right after installing Ubuntu. Had to put the patch for the graphic card, like to make it run as it's a basic graphic card. Now I notice it's very slow when it comes to InkScape operations and the screen is displaying a strange "refreshing" effect like it happened on CRT screens.

How do I check if my card is being recognized and running correctly?

TIA

Can you update the question with the exact graphics card model. –  mikewhatever Dec 6 '11 at 4:35
    
you can use the command lshw -c video to obtain info about your video card, you can also use a graphical interface thanks to the command jockey-gtk to manage additional drivers for your system. Please specify what you have done and what you mean with "patch". –  Micro Dec 6 '11 at 5:28
    
this is what lshw -c video gave me: *-display:0 description: VGA compatible controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:45 memory:90000000-903fffff memory:80000000-8fffffff ioport:6120(size=8) –  Nishant Vergani Dec 6 '11 at 16:15

This is the "patch" I did for the graphic card: Hi, what type of graphics unit do you have? I had the same problem with nvidia. At startup, when you are going to choose the operating system that you want to boot, mark ubuntu, press E, and change the words "quiet splash" to "nomodeset", if your graphics unit is nvidia. –  Nishant Vergani Dec 6 '11 at 16:23
