[XBMCbuntu] Intel G45 issues - anthistatic - 2012-02-10 Hi I'm almost afraid to post this, but I feel that I have no other option, so here goes... I am using an old laptop for mu XBMCbuntu-install. It features an Intel chipset and along with that an Intel GMA X4500 graphics chip. Not much us for anything but SD movies and such, but for the bedroom, it will suffice. The install of XBMCbuntu was rather painless, Some minor issues with pink-colored install windows, but it seemed OK anyway. OK, I'm not much good with Linux file systems and architecture, but I do know how to Google stuff up, but I'm at a total loss here... Upon reboot after finished install I connected my laptop through the HDMI-interface to my fullHD tv. an operation that use to work on Windows-based XBMC installations, but this is when the fun start... Upon connecting the HDMI and the computer booted up, the initial XBMC-splah seemed to display at high(est) resolution, but when the video driver was loaded, the screen just went crazy an any setting above 1024x768 just broke off and crammed that resolution onto the top-left corner of the screen. 1920x1080 wasn't even close to rendering properly, and getting a readable screen back was quite a pain... I've tried various solutions to this problem, but the thing is that most of the fixes adheres to nVidia cards and/or older versions of *buntu or XBMC-Live... For instance, I have no xorg.conf file. Trying to create a new one through the command; Code: sudo Xorg -configure That one gives a series of errors. I also tried to shut down gdm/lightgdm services beforehand, but that brought other problems. None of which has solved my problem... Where do I even begin to solve this issue! - alanwww1 - 2012-02-11 Hi! Some of the stuff might work on G45 from my guide: http://forum.xbmc.org/showthread.php?tid=114368 specially the custom modelines iin xorg.conf for standard hdtvs: Code: sudo wget http://paste.kde.org/6966/raw/ -O /etc/X11/xorg.conf But please check (the way I describe in the guide) if your used output is "HDMI2" like on mine. Let me know the results. - anthistatic - 2012-02-11 Thanks for a speedy reply, and my apologies for my tardy attempts at following your guide. The thing is that I'm running into some problem at a really early stage. ~vainfo returns: Code: Xfree86-DRI is missing on display ":0,0" and: ~glxinfo | grep vendor returns: Code: Error: Unable to open display. And I'm stuck right there... - alanwww1 - 2012-02-11 You tried those command in a too early stage :-) Like it is in the guide: Code: After this you can check if libva installed ok. with a command "vainfo" you should see something like this after you start the X server with "startx" and use vainfo there: You need to run the xserver first with startx if you are not already using some window manager. If you use ssh to install things, try to run the xserver and than on your TV or monitor you will see a black area where you have to click in with your mouse to get it active. Here you can type in the commands. Cheers, Attila - anthistatic - 2012-02-11 OK So I tried this again, this time via SSH/Putty... made things considerably easier. Still got the "Error: Unable to open display" but after running: Code: sudo stop lightdm and Code: sudo start lightdm I managed to get a functioning readout of the "vainfo": Code: johan@XBMCbuntu:~$ sudo start lightdm After this, running "xrandr -q" yet again presents me with: Code: Can't open display - alanwww1 - 2012-02-11 anthistatic Wrote:After this, running "xrandr -q" yet again presents me with: I think have a better solution for you. Just run it with ssh: Code: cat /var/log/Xorg.0.log |grep connected See which output is disconnected and which one is connedcted. - okeydokey - 2012-02-11 This may also help for running xrandr from ssh. NightStormWolf Wrote:You can also export the display so you can use xrandr: - alanwww1 - 2012-02-11 Thanks okeydokey ! :-) I'll add this to my guide. - anthistatic - 2012-02-11 After having done the Export Display=:0 I first tried the xrandr command, which worked properly this time, but since I now have my old laptop connected to my computer screen through ordinary VGA (and no, the 1680x1050x60 does not display properly either) I will not post the results of that query just now... However, I also tried the "glxinfo | grep vendor", which earlier gave me the same "Error: Unable to open display", and the results ware quite interesting... Code: johan@XBMCbuntu:~$ glxinfo | grep vendor That string seems a bit wrong, considering it is a Intel GMA X4500 card inside that laptop... - alanwww1 - 2012-02-11 The glxinfo output is ok. Have you tried my custom modeline xorg.conf with your HDTV ? On your computer screen with VGA it will surely not work, but on the TV ober HDMI, it should. But for that you need to run the xrandr -q when your TV is hooked up and get the proper output which is connected. - anthistatic - 2012-02-11 I have not tested your xorg.conf. Where can I find it? Will hook up my TV later on and try it as soon as possible after I get it... - anthistatic - 2012-02-11 Aaaah... You mean the one you import via: Code: sudo wget http://paste.kde.org/6966/raw/ -O /etc/X11/xorg.conf I actually haven't tried it as yet. I will return with results ASAP! /Static - anthistatic - 2012-02-13 anthistatic Wrote:Aaaah... You mean the one you import via: So, I've made some quick tests with connecting the lappy to the TV through the HDMI interface. Still no success. I have not yet had the time to perform and more conclusive tests, or even checked which interface are connected and which are not, tried a quick "xrandr" in the xbmc's own console (not SSH) but without any success even using the "export DISPLAY=:0" I'll try to do some more testing later tonight, but I'm not sure if I can get the TV to myself for that long I also noticed another thing during my quick test; If i put XBMC into windowed-mode, i can place the mouse-cursor outside of the area that displays the XBMC interface, but the cursor turns from a pointer into a big "X" when it moves outside of display-area. Is this of any significance? //Static - anthistatic - 2012-02-15 OK I might have found a solution. * I redownloaded the xorg.conf from here: Code: sudo wget [url]http://paste.kde.org/6966/raw/[/url] -O /etc/X11/xorg.conf * Discovered that my HDMI interface was called HDMI1 and edited xorg.conf accordingly. Afterwards, I ran the following commands: Code: sudo add-apt-repository ppa:xorg-edgers/ppa Rebooted the lappy with HDMI-cable inserted and, HEY PRESTO! Suddenly I was able to set my screen resolution to the full 1920x1080. The result is stunning on my 46" LG!!! I'm not entirely sure if I did anything else apart from the steps mentioned above., but adding the edgers repositories seems to have reinstalled and upgraded almost all the drivers inside my XBMCbuntu... Hopefully someone might be successful at trying those steps too. If so, write a line or two in this thread to tell of your progress, even if it doesn't confirm my steps as a possible fix. Cheers! RE: [XBMCbuntu] Intel G45 issues - chalk7777 - 2012-03-30 Hi all, I am also having issus with Intel. I can get a picture over HDMI but not good enough to watch anything. I have gone through a lot of threads, including this one, and tired many different things but still no go. I have added the linux repositories, done the updates added the xorg file, changed to HDMI1...... still get a crap looking picture. So I run the following: Code: xbmc@xbmc:~$ export DISPLAY=:0 Any help from here would be appreciated. Thanks, |
