slack 13.0 X sometimes fails to start after boot


about 50% of the time. linux says "starting X11 session" then i get a blank screen with a flashing cursor and absolutely nothing else. i can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. after that, i can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. i have reinstalled X and KDE twice now as well as deleting my .kde folder. this condition started when i inadvertently ran out of disk space on my /home drive. since then i have migrated /home to a larger drive and watch it's disk space very carefully.

try installing the manufacturer created drivers for your video card- i had the same problem with kdm and kde using the debian apt repo default drivers but once i downloaded the proper ones from nvidia and installed it worked fine

more info, and this time had the presence of mind to grab the last part of /var/log/Xorg.0.log.old

so this time i was able to find the errors i was looking for.

i looked at the manufacturer's website, and basically all they have is linux drivers for their very latest hardware, and say that my hardware's drivers are "included in the linux kernel and so are not maintained on the SIS website" or sonething to that effect... so here's the error when X hangs:
Code:
(II) SIS(0): Restoring by setting old mode 0x38
(WW) SIS(0): xf86UnMapVidMem: cannot find region for [0xb7789000,0x10000]

Fatal server error:

Please consult the The X.Org Foundation support 
	 at http://wiki.x.org
 for help. 
Please also check the log file at "/var/log/Xorg.0.log" for additional information.
it works fine sometimes at boot, it works sometimes when logging one user out and logging in as another user (but fails about half the time for either), but seems to always work for startx from a CLI prompt. another odd error in the Xorg log is this one:
Code:
(II) SIS(0): 
	Dear SiS76x user, your machine is using a shared memory framebuffer.
	Due to hardware limitations of the SiS chip in combination with the
	AMD CPU, video overlay support is very limited on this machine. If you
	experience flashing lines in the video and/or the graphics display
	during video playback, reduce the color depth and/or the resolution
	and/or the refresh rate. Alternatively, use the video blitter.
so not only do i have an onboard video chipset that isn't playing nice, the motherboard has a video chipset that doesn't play nice with the particular processor...

the video chipset is SIS761, and the cpu is an AMD Sempron

so i found this from http://www.winischhofer.net/linuxsispart1.shtml#13
Code:
3. A few words about the SiS 760 (all versions)
	

The SiS760 is a chipset for the AMD64 and AMD Sempron platform. These CPUs have a memory controller built-in, ie in systems based on these CPUs, there is no dedicated memory controller present.

As with all integrated SiS chipsets, the SiS 760 supports shared video memory, ie. memory that is shared between the system and the graphics (this technique is called "UMA"). However, the 76x also supports dedicated video RAM (so-called "local framebuffer memory" = "LFB") which connects directly to the graphics chip and is accessible for the CPU via the bus. Shared memory and local memory can be combined ("hybrid mode").

Shared memory is slower, because the graphics chip has to access it via the system memory bus, while it can access local framebuffer RAM directly. Most if not all modern graphics cards therefore use local video memory.

While shared memory was quite usable on all previous integrated chips (630/730, 65x, 661, 74x), there is a serious problem with it on the SiS760 - caused by the aforementioned fact that the CPU contains the system memory controller. This leads to severe memory bandwidth limitations if only shared system memory is used and no local framebuffer memory is present.

Therefore, the 760 - if used with shared memory only - is not really usable in dual head configurations; even in single-head operation, some features are limited. This especially affects video overlay support (Xv): Although the SiS760 supports two video overlays, these are in most cases not usable: Heavy flicker in the video and the graphics may occure as a result of exceeding the available memory bandwidth. The X driver takes some counter-measures on such systems (even advanced ones in the Premium Version), but it can't avoid the problems entirely. On systems with both shared and local video memory, the drivers will only use the local memory part. You may likewise disable the shared memory in the BIOS.

My advice: Don't buy a machine with a SiS760 unless this machine has dedicated local video memory. And please don't complain about "driver bugs" if you see "flashing lines" on the screen; these are the typical effects of a bandwidth problem and unavoidable - even the Windows driver can't do better. In such cases, reduce the resolution and/or refresh rate and/or color depth, or use one output (CRT1 or CRT2) only. Sorry, can't help it. There is no driver bug involved.

so i'll ask another question... how do i put the X11 session manager (which brings up the initial login screen) into a lower resolution video mode (it's currently at 1440x900 )?

Your Xorg log shows this.

Your link in #4 shows this.

Have you checked your BIOS settings to see if you can disable the shared memory?

You set this in /etc/X11/xorg.conf

ok, maybe it's just because it's 1:30 in th morning here and i'm just not "getting" it.... what needs to be in xorg.conf to make 1280x800 the default resolution? there currently are no resolution settings in xorg.conf:

are you using an older toshiba laptop? They have some known problems with acpi and video problems on certain distros and linux kernels and so you may have to disable acpi in your bios settings

ok, so i added the modes line, and X wouldn't come up at all, error in the log was it was expecting a dot clock setting on a ModeLine, and there weren't any mode lines. i tried reinstalling X, no luck. i finally went and renamed xorg.conf.vesa as xorg.conf and it seems to work. i won't know for sure until i either reboot or log out of my user account and try to log in as root, or another user.

edit: ok, tried logout and back in... working so far. i'm not ready to mark this as solved just yet, but it is better than it was.... here's the current xorg.conf:

unfortunately now my max resolution is 1024x768, so i guess i need to add a ModeLine and add "1280x800" to the modes listing under screens??

It would be better to get X working with the 'sis' driver rather than the 'vesa' driver.

Please post the contents of /var/log/Xorg.0.log after you try to start X using the /etc/X11/xorg.conf in post #6. This should show the modes that your setup can support.

the problem is that when i select the ones i want and put them into xorg.conf, x errors out saying "screen not found". either i put them in the wrong place in xorg.conf, or i'm missing another part of the process somewhere i strip off the stuff before ModeLine and put them in the "monitor" section, then put the corresponding Modes "1280x800" "1024x768" etc... in the screen section under the Depth=24 line.

if anybody has a linux box with a Sempron3000 and SIS761 video hardware that's working properly, it would really help if i could see your /etc/X11/xorg.conf

Have you tried a ModeLine entry in the Monitor section of xorg.conf?
Code:
Section "Monitor"
	#DisplaySize	  410   260	# mm
	Identifier   "Monitor0"
	VendorName   "ACR"
	ModelName    "X193W"
	HorizSync    30.0 - 82.0
	#VertRefresh  50.0 - 75.0
	VertRefresh  49.5 - 75.0
	Option	    "DPMS"
	ModeLine "1280x800"   83.52  1280 1344 1480 1680  800 801 804 828 +hsync +vsync
EndSection
I have taken the ModeLine from the output in the Xorg.0.log. I note that this is reported for a frequency of
49.7 kHz. This is very slightly below the minimum value set for the VertRefresh in the Monitor section. I suggest you also set VertRefresh 49.5 -75.0.

actually 49khz would be the horiz sync frequency, not the vertical frequency.

i tried that, and got X dumping out saying "screen not found"

i'll try it again and read through the xorg.conf man page again and see if i can figure anything out

looks like i'll have to try adding a video card... not exactly the answer i was hoping for, but i really need to be able to have the capability to log out and log in as other users in X, and that function isn't available without the session manager working.
