I have installed Suse 11.4 on my new laptop, an Acer Aspire 7551G. According to Acer's product description the computer has a WSXGA Display with 1600x900 pixels. My X runs well, but I have the impression that it uses a smaller resolution than 1600x900. So I have two questions: 1. How can I determine the resolution used by my X? 2. In case it is lower, how can I force X to use 1600x900 px? Thanks advance for you help and best regards, Wolfgang -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It's a 17.3 inch screen that has a native resolution of 1600x900.

Why start so complex? Can't we just start simple, and use the tools provided by the desktop manager? Or have I missed something? Open the Display configuration and look at what it's set to. In KDE4 for example go to: KMenu > Configure Desktop > Hardware > Display and Monitor > Size & Orientation What does it say there? Does it say 1600x900? If not, can you set it to the right resolution? Gnome's path is similar, and the result should be the same...

Following your advise, I found a size of 1024x768 in "Size & Orientation". The tool gives me the choice between this value and "Disabled", but 1600x900 is not available. So I selected "Disabled" (whatever that means), but that did not help. After closing the tool and recalling it, the old value of 1024x768 appeared again. Now, since SaX2 has been abolished, there is obviously no way any more to set up the correct size. Obviously, Suse is no more reliable. Perhaps, I should try a different distro.

Don't discount Felix's advice... I was just suggesting we start simple... sometimes the solution is simple. Another distro won't help you. ALL top distros will give you similar results because they all use the same autodetect for X resolutions. If it fails in openSUSE, it's quite likely to fail in the rest. You cannot claim wildly that "obviously Suse is no more reliable" because this is not an openSUSE specific issue... it's an issue with X not being detected correctly.. this is NOT something unique to openSUSE. What video card does your laptop have? What video driver are you using? Generally if you've only got 1024x768 then the install routine didn't detect something correctly Felix asked for the extra info you have to provide to take this to the next step. My guess is something went wrong in the install... that laptop should generally work fine with whatever Linux you install on it. SAX2 did a great job back when X wasn't able to detect things.. now it's generally redundant because xorg.conf is depricated.... as in it's obsolete. SAX2 was created because there was nothing at the time to set up X.. now there is.... Yes I know, there are cases where an xorg.conf is still needed, but they are uncommon. I honestly don't think a SAX2 solution is right in this case (of course I could be wrong)... I'd guess that once it's sorted, the X autodetect will do its job and your X resolutions will be what they should be.

Typo on my part. The "now there is" wasn't supposed to be there... it was a bit of another train of thought I deleted... and I missed that bit. There is a GSoC that is looking into a SAX3 (I think.. I read about it, but I don't know its status), but... until it's complete, I wouldn't bank on it. As for what replaces SAX2... the autodetect in X replaces it. There is no need for an app like SAX2 in most cases. On most hardware, the display is detected correctly and all display modes are available. SAX2 is simply redundant... it was used to set up a working xorg.conf file when there was nothing else in place to do so. Yes you could call it when needed - back when X didn't autodetect your display and video hardware... back when if you didn't cobble together an xorg.conf, either by yourself, or using SAX2, you had no hope of getting a working X environment. Now xorg.conf is deprecated... so SAX2 is no longer useful... no longer maintained... and no longer included. Now before someone pops up and says yah but my monitor yadda yadda, I didn't say all... I said most. Everyone here has acknowledged that there are "corner cases" where X fails to autodetect... either because of an explicit bug - which from what I read in this thread is highly likely to be the OP's problem, or because the hardware is unusual/odd or has special case needs. These special cases are NOT the majority. These are uncommon... very uncommon. The vast majority of displays - even hardware like my Toshiba TV - are autodetected correctly, and there is nothing else to do. Where it does fail, submit a bug report... help get it fixed so that next time around it does autodetect the unusual hardware correctly. If the community sees a need for reviving SAX2, then they probably can do so. No one is stopping them. When SAX2 was discontinued, there was a call put out for maintainers, and the silence was deafening. No one was interested in maintaining it... so it was dropped. You can do some manual display tweaking using xrandr - there have been a few threads about this here on the mailing list. C. PS: just an a related aside... the autodetect in X detects and configures my older Toshiba LCD TV without any hassle (set to a native resolution of 1366x768). Windows 7 can't set it up correctly at all regardless of using the latest video card drivers or using the Windows 7 generic video drivers. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

They're more common than you seem to think. http://fm.no-ip.com/Tmp/Hardware/Display/ represents 14 displays (14 out of 16 functional in the building): 1 Vizio HDTV 1 Viewsonic 1400x1050 LCD 1 Dell shadowmask 1 Dell 1600x1200 LCD 1 Dell 1400x1050 laptop 3 Dell Trinitrons 3 IBM Trinitrons 1 Sony Trinitron 2 NEC shadowmasks 1 NEC, the laptop, and all 3 Dell Trinitrons, 5 of 14 total units, have no EDID. A few of those datasets represent additional EDID failures, but those were all corrected by a cable change. IOW, not only can a display itself have bad EDID, but a cable problem also can cause EDID failure. Not all cables with 15 pins showing have wires connecting all that need connecting. Some don't even have pins in all 15 positions. Trinitrons normally deteriorate with age, but Sony software can be used to adjust them to extend their lives. Using that software apparently can invalidate the EDID checksum. -- "The wise are known for their understanding, and pleasant words are persuasive."

So far the only solution I can find (tried configuring X manually) is to use xrandr to add and set the mode. Your should:

1. Run:

,---- | hwinfo --monitor | grep 1600x900@ `----

to find the Hz that that mode runs at.

2. Generate a modeline with cvt:

,---- | cvt 1600 900 `----

3. Now put this in your /etc/X11/xinit/xinitrc.common:

,---- | /usr/bin/xrandr --newmode<modeline> | /usr/bin/xrandr --addmode VGA1<mode name> | /usr/bin/xrandr --output VGA1 --mode<mode name> `----

for example, this is what I have in mine:

,---- | /usr/bin/xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync | /usr/bin/xrandr --addmode VGA1 1680x1050_60.00 | /usr/bin/xrandr --output VGA1 --mode 1680x1050_60.00 `----

I presume that your display is vga1, if not, you can find out with:

,---- | xrandr --verbose `----

This last statement did not give me any information on the display type, but produced the following error Message: ,---- | xrandr: Failed to get size of gamma for output default ,---- But anyway, having no different chance, I assumed VGA1 to be the correct display type. So, I invoked hwinfo and cvt, using the values produced by these programs for adding the following lines at the head of /etc/X11/xinit/xinitrc.common: ,---- | /usr/bin/xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 \ 2112 900 903 908 934 -hsync +vsync | /usr/bin/xrandr --addmode VGA1 1600x900_60.00 | /usr/bin/xrandr --output VGA1 --mode 1600x900_60.00 ,---- Then, pressing ALT CTRL F1, I went to a black screen where I dropped X by typing '/etc/init.d/xdm stop'. Then I restarted X, typing '/etc/init.d/xdm start'. After having logged in again, I noticed that nothing had changed, i.e the screen size was still 1024x768. Now, I moved the additional lines, i.e. those beginning with '/usr/bin/xrandr', to the end of /etc/X11/xinit/xinitrc.common, went to a black screen and dropped and restarted xdm. Again no effect. After these failures I replaced VGA1 by WSXGA in both versions of my /etc/X11/xinit/xinitrc.common, i.e. at the beginning and at the end and repeated the boring procedures described above: No effect again.

When I specified a wrong number, a list appeared with a lot of different sizes and color depths, the largest of which was 1152x864/32. Some types were VGA, others VESA, But my 1600x900 did not appear. All the sizes offered had a width-to-heights ratio of 4:3, never of 16:9.

Try uncommenting the line in 50-device.conf (also see below). If that doesn't work you can try the package xorg-x11-driver-video-radeonhd:

http://wiki.x.org/wiki/radeonhd#SupportedHardware

Uncommenting '#Driver "radeon"' in 50-device.conf did not work, of course. So I went to http://wiki.x.org/wiki/radeon where I found a link to http://cgit.freedesktop.org/xorg/driver/xf86-video-ati which contains list of available drivers. I downloaded the most recent one, i.e. xf86-video-ati-6.14.1.tar.gz. After unpacking this file, I found, among other files, a script called autogen.sh which has to be executed for installation: ,---- | #! /bin/sh | srcdir=`dirname $0` | test -z "$srcdir" && srcdir=. | ORIGDIR=`pwd` | cd $srcdir | autoreconf -v --install || exit 1 | cd $ORIGDIR || exit $? | $srcdir/configure --enable-maintainer-mode "$@" `---- But execution failed because autoreconf, invoked in the third last line, is not supplied.

...

I also found this:

,---- | Identifier "Default Device" | | #Driver "radeon" | | ## Required magic for radeon/radeonhd drivers; output name | ## (here: "DVI-0") can be figured out via 'xrandr -q' | #Option "monitor-DVI-0" "Default Monitor `----

in /etc/X11/xorg.conf.d/50-device.conf

As already mentioned above, uncommenting '#Driver "radeon"' did produce any effect. Now, I feel I bothered you (and myself) too much. So, I decided to renounce further attempts. Being able to work very well with the resolution of 1152x864, it' no problem for me to wait for a new version of OpenSuse, 11.5 or 12.0 or whatever else it may be. Anyway, I owe you a lot of gratitude: thank you very, very much, Charles!

Meanwhile I have installed the autoconf package from the Suse CD.

I have installed Suse 11.4 on my new laptop, an Acer Aspire 7551G. According to Acer's product description the computer has a WSXGA Display with 1600x900 pixels. My X runs well, but I have the impression that it uses a smaller resolution than 1600x900.

What size is that screen?

The size of my screen is 17.3".

...

...
So I have two questions:

1. How can I determine the resolution used by my X?

1-Load in a web browser http://fm.no-ip.com/Auth/dpi-screen-window.html and/or 2-Open KInfoCenter -> Xserver and/or 3-'xdpyinfo | grep dime'

...
2. In case it is lower, how can I force X to use 1600x900 px?

Really hard to answer that without knowing the output of 'lspci | grep vga' and/or output from 'hwinfo --gfxcard'.

"lspci | grep vga" produces no result, but "lspci | grep VGA" shows this line: 02:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour \ [AMD Radeon HD 6470M] And here follows the response of "hwinfo --gfxcard" "25: PCI 200.0: 0300 VGA compatible controller (VGA) [Created at pci.318] Unique ID: B35A.mAJbyLlkeA6 Parent ID: _Znp.XY83zNTsW5E SysFS ID: /devices/pci0000:00/0000:00:02.0/0000:02:00.0 SysFS BusID: 0000:02:00.0 Hardware Class: graphics card Model: "ATI VGA compatible controller" Vendor: pci 0x1002 "ATI Technologies Inc" Device: pci 0x6760 SubVendor: pci 0x1025 "Acer Incorporated [ALI]" SubDevice: pci 0x0388 Memory Range: 0xc0000000-0xcfffffff (ro,non-prefetchable) Memory Range: 0xd0000000-0xd001ffff (rw,non-prefetchable) I/O Ports: 0x9000-0x9fff (rw) Memory Range: 0xd0040000-0xd005ffff (ro,non-prefetchable,disabled) IRQ: 5 (no events) I/O Ports: 0x3c0-0x3df (rw) Module Alias: "pci:v00001002d00006760sv00001025sd00000388bc03sc00i00" Config Status: cfg=no, avail=yes, need=no, active=unknown Attached to: #8 (PCI bridge) Primary display adapter: #25 Moreover I list the contents of /etc/X11/xorg.conf Section "Device" Identifier "vboxvideo" Driver "vboxvideo" EndSection Section "Screen" Identifier "vboxvideo" Device "vboxvideo" EndSection Section "Device" Identifier "vmware" Driver "vmware" EndSection Section "Screen" Identifier "vmware" Device "vmware" EndSection Section "Device" Identifier "cirrus" Driver "cirrus" EndSection Section "Screen" Identifier "cirrus" Device "cirrus" EndSection Section "Device" Identifier "fbdev" Driver "fbdev" EndSection Section "Screen" Identifier "fbdev" Device "fbdev" EndSection Section "Device" Identifier "vesa" Driver "vesa" EndSection Section "Screen" Identifier "vesa" Device "vesa" EndSection Section "ServerLayout" Identifier "Layout" Screen "vboxvideo" Screen "vmware" Screen "cirrus" Screen "fbdev" Screen "vesa" EndSection I hope these data are helpful.
