All of a sudden, the graphics aren't working on my Ubuntu 13.04 64bit. I ran sudo apt-get upgrade yesterday, and now the launcher and dash transparency don't work. What's odd is that the notifications transparency-blur-thingy does work. Auto-hiding the launcher also gives me weird results. I have some screenshots:

enter image description here
The launcher is not transparent. enter image description here Neither is dash. enter image description here
And that is what the desktop looks like with the launcher on auto-hide.

My hardware is a Gigabyte h61n motherboard with an intel i3 CPU. What's wierd is that System Settings -> Details can't make up it's mind what graphics I have.

the output of lspci -nnk | grep -iA3 vga:

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0102] (rev 09) Subsystem: Gigabyte Technology Co., Ltd Device [1458:d000] 00:16.0 Communication controller [0780]: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 [8086:1c3a] (rev 04) Subsystem: Gigabyte Technology Co., Ltd Device [1458:1c3a]

Where the lines "Kernel driver in use:" and "Kernel modules:" missing or you didn't copy them? Also edit your question by adding more information about your hardware. If it is a laptop, then usually model name is enough. Mos Have you tried "sudo apt-get dist-upgrade"? (update with dependencies) Also run "sudo apt-get install xserver-xorg-video-intel" to make sure that for some reason driver has not been removed. –  Tanel Mae Jun 9 '13 at 9:29
    
@TanelMae I think I copied everything, but here it is again: 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0102] (rev 09) Subsystem: Gigabyte Technology Co., Ltd Device [1458:d000] Kernel driver in use: i915 00:16.0 Communication controller [0780]: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 [8086:1c3a] (rev 04) –  MadTux Jun 9 '13 at 9:39
    
Test whether you have the driver installed as instructed in my previous comment. Let's hope it is just a driver issue. –  Tanel Mae Jun 9 '13 at 9:45

Sometimes things get broken or lost during updates.

Try these two commands:

sudo apt-get dist-upgrade 

This reruns updates command with some extra features. Read about the difference between apt-get upgrade and apt-get dist-upgrade here.

sudo apt-get install xserver-xorg-video-intel

This reinstalls the driver if it has been removed for some reason.

Yeah, I have noticed that the graphics drivers in the Ubuntu versions since 12.04 have been a bit troublesome. Generally when I see issues like this I just recommend reinstalling the graphics driver. I am not sure if you are using and nvidia or ati card, but try reinstalling the driver. This will force a recompilation of the drivers and will hopefully solve the issue. You can do this through instructions like

sudo apt-get install --reinstall nvidia-current 

You could do the equivalent thing for the ATI driver as well.

I have an integrated intel graphics chip. What do I do? –  MadTux Jun 9 '13 at 9:24
    
Here is the link for the intel drivers. Just download and install these. Hopefully that will help –  krishnab Jun 9 '13 at 9:43

what graphics card you have exactly ? concerning nvidia there is actually a suiting package for CUDA optimus. –  dschinn1001 Jun 9 '13 at 10:20
    
I have an intel h61 chip. Everything works, except the launcher and the dash. But, @TanelMae solved it. –  MadTux Jun 9 '13 at 17:09
