The Intel graphics fanboys are going to livid about this :)
Just joined phoronix - seems like a lot of knowledgeable people here, and I'm having a problem with my HD5450 that is beginning to drive me crazy, so maybe someone can give me hints on where to look.
I'm running Ubuntu Lucid 64-bit for my Desktop system - I have no problem upgrading to 10.10 if it will help, but I kind of like the idea of using the long term release. I mainly use it for web development, and web browsing, no games fancier than minesweeper or Freecell. I do like Compiz, for a couple of features, and I have two 19" LCDs. This all works very well, and the only complaint is the login prompt comes up on the wrong monitor, but I can live with that (and could probably fix it if not).
But there is a problem that bugs the hell out of me. Most of the time, right after the grub menu, the text screen gets screwed, so it only displays a single line at the top with colored pixels forming random patterns. The memory-test option causes a reboot, and the virtual terminals all have this same strange mode. I think the VTs are working, as I can see the patterns changing, but can read nothing. I can always get back to the graphics screen with Alt-F7 (or sometimes F8).
If I need to choose the recovery mode, that also does not display correctly.
I'm not sure what drivers are even active at this point. Any help on where to look, or even where not to look, would be appreciated.
Another useful thing is to either run glxinfo and look at the first part of the output or run glxinfo | grep render to pick out the line with "renderer" information.
Final thing is to run dmesg, save the output in a file, then you can look at messages from the kernel driver. You get messages from a number of different drivers mixed together but the graphics messages will jump out after a while.
direct rendering: No (LIBGL_ALWAYS_INDIRECT set),
OpenGL renderer string: ATI Radeon HD 5400 Series
Not sure what you mean for me to look for here.
Thanks for the quick reply. Hopefully, I'll get this problem solved one way or another.
If you are running the open drivers then kms will have come up (modesetting code in the open source kernel graphics driver) and I *think* you will be running on "fb" devices created by the kms driver. If you are running the proprietary driver then that stack won't be running yet and you'll be running a different fb driver.
I don't know an easy way to tell what driver is running during bootup so I figured it would be easier as a first step to figure out what driver is running after boot and work backwards from there ;)
So, using the GUI, I went to the System Menu, Administration, Hardware Drivers, and I disabled the driver there, rebooted, tried the memory test, and it rebooted, tried the recovery mode, got the garbage, hit Ctrl-alt-delete, and then it worked correctly all the way. Lots of text output, all the VTs working.
I went back to the Hardware Drivers, and now I get the confusing part: It says "Proprietary drivers are being used to make this computer work properly"
It lists ATI Fire GL, and has the "Activate" button enabled. next to the button, it says "A different version of this driver is in use".
My other Ubuntu system has an old NVidia card, and it always had only 2 choices - either use or not use the proprietary driver. This system seem to also have 2 choices, but they are use one or another proprietary drivers, and we'll leave it to you to figure out which is which.
Is this normal? Should I go deeper and remove all the ATI drivers? Everything seems to work the same as before, fwiw. I even still have the same Catalyst Control Center.
My motherboard came with ATI onboard, which I disabled. Maybe there are drivers left over from that?
I have nothing positive to contribute to this thread. Just don't buy a 5450. They are a very low powered card. I purchased one and am very dissapointed with my purchase. It works, it just is a VERY low powered card.
Spend the extra on something with more power.
Personally, I like the card I got - there's no fan, so it's quiet. Who wants to go deaf from all the loud fans on multiple computers? It cost me $35 - $40 after a rebate, has plenty of horsepower for what I need - running Compiz with Ubuntu.
After reinstalling Ubuntu, it works well now. May have been the installation, or may have been the fact that I switched from 64-bit to 32-bit, but everything works fine now.
People who make flat statements about how much power everyone needs without qualifying the application obviously don't understand value.
