It has been suggested (elsewhere in this thread) that the i810 driver depends on the vesa mode list, but the intel driver does not. My next option will be to change the config files to use the intel driver as opposed to the i810 driver (which is what the original configuration picked automagically). -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software-- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com
Problems with widescreen (16:9) under CentOS 5 w/ xorg-x11-drv-i810-1.6.5-9.40.el5
I am the tech guy for a local library. We have a network containing several diskless workstations. The hardware are these P4 boxes: http://www.geeks.com/details.asp?invtid=SAMBA845V-24-4-Rcat=SYS (We have inserted additional memory, bringing most of the machines up to 1.25Gig of memory, and two up to 2Gig of memory.) These little machines have integrated Intel video chips on their motherboards and have both VGA and DVI connectors: (II) I810(0): VESA VBE OEM Vendor: Intel Corporation (II) I810(0): VESA VBE OEM Product: Intel(r)845G/845GL/845GE/845GV Graphics Controller (II) I810(0): VESA VBE OEM Product Rev: Hardware Version 0.0 (II) I810(0): Integrated Graphics Chipset: Intel(R) 845G (--) I810(0): Chipset: 845G And the i810 driver seems to be happy to talk to these chips. I am using the stock (distro supplied) RPM: xorg-x11-drv-i810-1.6.5-9.40.el5 The machines are running pretty much stock CentOS 5.8 (I am slightly behind on some updates). These machine boot off the network and then mount their root (/), /usr, and /home file systems via NFS from the server and function otherwise as normal workstations. And they work great with 4:3 monitors. Recently, because of new cataloging and circulation software which seems to have been designed by (open source) developers who probably have new widescreen monitors on their machines, we have put widescreen (16:9) monitors on three of the machines (various menus and toolbars don't fit on a 4:3 monitor, even at 1280x1024 [19-20 monitor]). But we are having some problems getting the proper aspect ratio (or even a display at all) on two of the three. First of all, using the VGA connection, the X server *refuses* to use any Modeline that is not a 4:3 aspect ratio. It seems that the X server presumes that *all* VGA connected monitors are 4:3. (All three of the new wide screen monitors do have 15-pin VGA connections, so this 'presumption' is obviously false, esp. since the monitors using DDC while connection via VGA are suggesting 16:9 mode lines.) I got *one* of the machines to correctly use a 16:9 aspect ratio Modeline (1600x900) using the DVI connection. The other two don't work. One won't display anything (claims that the video is missing or wrong). And the other just uses something like 640x480. Both monitors work just fine on DVI in console display mode (bare kernel VGA), so the video card is seeing the monitor and sending it a signal at that level. I have tried everything I can think of. The various log files and config files are here (each tar file contains one log and one config): This is the *working* machine (HP W2072a): http://www.deepsoft.com/wp-content/uploads/2012/09/catalog-DVI-1600x900.tar.gz These are for a (not working) Acer X223W: http://www.deepsoft.com/wp-content/uploads/2012/09/clearwater-VGA.tar.gz http://www.deepsoft.com/wp-content/uploads/2012/09/clearwater-DVI.tar.gz From xdpyinfo while connection via VGA: screen #0: dimensions:1680x1200 pixels (474x302 millimeters) resolution:90x101 dots per inch And for a (not working) ViewSonic VA2431WM: http://www.deepsoft.com/wp-content/uploads/2012/09/circdesk-VGA.tar.gz http://www.deepsoft.com/wp-content/uploads/2012/09/circdesk-DVI-1600x900.tar.gz http://www.deepsoft.com/wp-content/uploads/2012/09/circdesk-DVI-1440x900.tar.gz http://www.deepsoft.com/wp-content/uploads/2012/09/circdesk-DVI.tar.gz From xdpyinfo while connection via VGA: screen #0: dimensions:1600x1200 pixels (521x290 millimeters) resolution:78x105 dots per inch We would really like square pixels -- is it possible or not? -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software-- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

It's not the X server's fault. The i810 driver, when it comes to output setup, is no better than the vesa driver. It can only set modes that happen to be listed in the video BIOS, regardless of what the display happens to claim to support. Since most 845 video BIOSes predate the wide availability of 16:9 monitors, they naturally tend not to list any 16:9 modes. RHEL5 (and therefore CentOS 5) does include an additional video driver for Intel graphics chips called 'intel' instead of 'i810', which does not have this limitation. I don't recall offhand whether that version worked correctly with 8xx-series chips; it might, I don't think I went out of my way to disable that, but if it doesn't work you get to keep both pieces. Alternatively, go search for 'i915resolution', which will allow you to override Intel VBIOS mode lists (and yes it does work on 8xx chips despite the name). - ajax ___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

I have two working 845G systems, but I don't try to use them with non-4:3 displays or with CentOS, so there's probably little more help I can give given what Adam Jackson already wrote in thread. Most of the 845G systems I've run across include AGP slots. Dell equipped many of its 845G Optiplex machines with Radeon 7500 AGP cards. There are many cheap new and used AGP cards around that do support widescreen modes, e.g. http://www.geeks.com/details.asp?invtid=9250-AGP-128-PBcat=VCD http://www.ebay.com/itm/ATI-Technologies-ATI-Radeon-7500-100-711014-64-MB-DDR-SDRAM-AGP-4x-Graphics-/140851713660?pt=PCC_Video_TV_Cardshash=item20cb6a967c http://www.ebay.com/itm/Sapphire-Technology-ATI-Radeon-9250-100582-128-MB-DDR-SDRAM-AGP-8x-Graphics-/140852649792?pt=PCC_Video_TV_Cardshash=item20cb78df40 BTW, installing an AGP card constitutes a RAM upgrade, as 845G chips use/share main motherboard RAM. -- The wise are known for their understanding, and pleasant words are persuasive.
