<p>Graham: </p> <hr /> <div>== T43 with Intel Graphics Media Accelerator ==<br /> <br /> My T43 (1871-FYG) with Intel 915GM is also affected by the problem and the 'ATI' sollution with<br /> acpi_sleep=s3_bios works. Please consider updating the page (I don't dare to do it myself).<br /> <br /> == From my experience, this does not work with TP R50e. ==<br /> <br /> If you want to be able to resume, you need :<br /> * To start from a VT<br /> * No option acpi_sleep<br /> * to save the PCI state like:<br /> cat /proc/bus/pci/00/02.0 &gt; /var/cache/video.config<br /> * Once you get back, restore it:<br /> cat /var/cache/video.config &gt; /proc/bus/pci/00/02.0<br /> <br /> However, the X screen is not clean after the restore, so this is not very useable...<br /> <br /> == The comment on R50e ==<br /> <br /> There is a comment at the end of the page on R50e, saying that you should switch to console first, and look at a page to learn how to do this.<br /> <br /> However. it seems to me that the given script already does it. Should the comment be removed?<br /> ----<br /> The scripts are different. However, if you can approve that the solution provided on this page resolves the problem, please remove the footnote.<br /> <br /> [[User:Wyrfel|Wyrfel]] 14:46, 17 Oct 2005 (CEST)<br /> ----<br /> On my R50e, the script on this page works fine, while the one linked in the footnote quickly wakes up from sleep.<br /> <br /> [[User:Thisnukes4u|Thisnukes4u]] 19:39, 1 Jan 2006 (CET)<br /> <br /> == Problems with R51 and Intel Graphics ==<br /> <br /> The problems described on the page occur intermittently<br /> with an Intel Graphics card on an R51. Here is what happens:<br /> <br /> 1. One some occassions everything seems to work fine.<br /> <br /> 2. On other occassions the screen looks OK but the some plane seems to have vanished. New text on the screen overwrites instead of replaces prior text. The &quot;standard&quot; pattern disappears from the X background.<br /> <br /> 3. On yet other occassions the X server dies and comes out &quot;blank&quot; in the mode (2) above.<br /> <br /> 4. The above problems appear only with the &quot;i810&quot; driver. The &quot;vesa&quot; driver works fine. Moreover, if the machine is &quot;suspend-to-disk&quot;ed then the problem disappears on resumption once the X server is killed and re-started.<br /> <br /> But for 1 and 4 above I would have given up and either avoided suspend to ram altogether or used vesa mode---as it stands the problem is tantalising.<br /> <br /> Kapil kapil at imsc dot res dot in<br /> <br /> == X40 with an Intel 855GM Integrated Graphics Device ==<br /> <br /> I used the {{bootparm|acpi_sleep|s3_bios}} boot parameter and the following ACPI script:<br /> <br /> #!/bin/sh<br /> set -e<br /> <br /> vt=`fgconsole`<br /> chvt 12<br /> echo mem &gt;/sys/power/state<br /> vbetool post<br /> chvt $vt<br /> <br /> The {{bootparm|acpi_sleep|s3_bios}} boot parameter alone did not fix things, and neither did saving and restoring the information from {{path|/proc/bus/pci/00/02.0}}.</div>
