WXGA Resolutions making me crazy....

[fontosaurus]

Okay, so I have a brand spankin' new Dell XPS M140. The onboard graphics card is an Intel Media Accelerator 900 -- nothing grand. When I first got everything installed, the system would boot into 1024x768 mode, when the primary hardware-wise is 1280x800. Looks pretty crappy, esp. if I'm going to be running the GIMP on here.

Anyway, I've been tinkering around with my xorg.conf file, and after adding the HorizSync and VertRefresh to the file, it allowed me to choose between 640x480, 800x600, and 1024x768. A "sort of" impovement, in the manner of, "Well, now at least you have some options."

I'm starting to wonder if this doesn't have something to do with my selection of the i810 driver? I'm guessing that that's it... I've attached my xorg.conf file here, to see if anyone's got any ideas on the matter.

I had the problem with my onboard intel 855. I solve by downloading a program called "855 resolution". after installing type this in the command line

"sudo gedit /etc/default/855resolution"

and put in mode 49, x = 1280 and y = 800.

then do dpkg reconfigure xerver-xorg

Okay, that, for some reason, dumped me into 640x480 (ouch!), but I was able to revert to a backed-up copy. Nowthen, I tried doing this:

sudo /usr/sbin/855resolution -l

And none of the modes came back with the proper resolution. Mode 49 reports as 1280x1024, and none of the modes report 1280x800, which is the monitor's natural resolution.

Any further ideas?

[kingsidy]

you actually type that in after you install the 855 package. Then reconfigure xorg. In my case i put mode 49, and then i inputted 1280 and 800 manually while the file is being edited. Then restart and see what happens. I f the resolution does not go to the native resolution, then reconfigure your xorg.

I don't mean to hijack the thread and all, but is Linux difficult about 16:10 resolutions? I'm thinking of buying an 1680x1050 screen and I'm using a NVidia 6800.

Yep. I did this:
1. Install 855 package.
2. Modify /etc/default/855resolution
3. reconfig xorg
4. restart
5. pull hair out

Hi,

I just got my own brand spanking (so to speak) new XPS M140. It has the linux i915/i910 driver in it. I was about to ask if your problem had been fixed, but instead I can now tell you what worked for me.

First of all, I tried the i810 drivers but it never worked. First it said there wasn't anything for PCI:0:2:0, so I added the BusID. Then it said there wasn't anything for PCI:0:2:1. Um... there's no external monitor. So I wrote a dummy device and monitor profile for PCI:0:2:1 and then it said it couldn't find the monitor. So I'm stuck with VESA.

During the original configuration (during initial installation, when I selected VESA), it found the HorizSync 28-49 and VertRefresh 43-72. I don't know if those numbers are wrong or not, but I read all the documentation and could neither confirm nor deny it. It wasn't worth calling Dell to figure it out, so I left it.

Next, I replaced index 49 with 1280x800. I never use 640x480, and I wanted to avoid any possible problem if I stuck in an external monitor that actually did have a higher resolution than 1024x768.

I had the same problem you described with 855resolution. I downloaded it directly and rebuilt it, and replaced the version in /usr/sbin with the one I built. Before, when I did the "855resolution start", it would say it worked but not actually change anything, just like you described. Now the changes stay put. You can download the 855resolution directly from http://perso.wanadoo.fr/apoirier/.

Next, the line that I think is the only one that really mattered: despite all of that, all I managed to do was remove the "640 x 480" resolution from the options when I started X. (Well, except for when I was trying to use i810, then X wouldn't start at all.) I finally found the right modeline:
Modeline "1280x800" 80.58 1280 1344 1480 1680 800 801 804 827

If you have a driver other (i.e., better) than the i915/i910, then this probably won't work for you. I did a google search for "modeline 1280x800 xps", and it was one of the many that came back. I have no idea how I would have figured out that was 827 and not 828. If you have one or many of the XPS upgrades, you can find a better Modeline that will work for you. I just put them all in, and saw to my shock that it worked -- then I commented them out one at a time until it broke.

I commented out some of the loaded modules, too, but they weren't the problem for me and I put them all back. They may affect performance, but they don't seem to matter as far as just getting it to work.

The result: it boots into 1280x800, and I can switch to 1024x768, or 800x600. I could probably get 640x480 by moving 1280x800 to some other location in 855resolution, but that's not important for me.

This process works for me also.

1. installed 855resolution using apt-get

2. changed /etc/default/855resolution

MODE=49
XRESO=1280
YRESO=800

3. changed xorg.conf Montior Section

HorizSync 28-64
VertRefresh 43-60
Modeline "1280x800" 80.58 1280 1344 1480 1680 800 801 804 827

4. rebooted

I don't know if all these steps are actually needed but it does work on my Dell Inspiron B130 with a 15.4" monitor.

One thing confuses me about this though. My card and chipset are actually not the i810, but i915. The 855resolution hack is intended for the i810 drivers (which I do have on another laptop) to make it think that it's capible of displaying 1280x800.

Another post on this forum recommends intalling the i915 drivers from freedesktop.org website, but the steps are not super clear, so i have not tried it. I wonder if this driver is better and would support the native 1280x800 resolution without any hacks. If so then we should have an ubuntu package for supporting i915 drivers.

[slackn]

I have just joined you all on my journey forward. I just got my new system today and installed it and was pulling out my hair. Thanks for this post. It is good to see others out there running ubuntu on the XPS M140. Thanks again everyone.

Any other pointers going forward with this machine??

I noticed and error of "apm:bios not found" on shutdown

Any tips for this system are appreciated.

[nik]

The i915 driver is included with the i810 driver... A bit confusing

There is a modified version of 855resolution, called 915resolution. It's in the depos, cant remember which one... It worked great for me, just installed with synaptics and followed the README.debian instructions.

I believe they are working on fixing xorg, but nothing so far...
