compiling linuxwacom on 10.1.3 on XO-1
Hi- I've been trying to get Colors! and the Wacom Bamboo tablet working for my 2 nieces for Christmas. I've been trying to build the driversr from the latest linuxwacom sources at: http://prdownloads.sourceforge.net/linuxwacom/linuxwacom-0.8.8-10.tar.bz2 Following the mini-HOWTO from http://linuxwacom.sourceforge.net/index.php/minihowto I've been able to get /./configure --enable-wacom' to complete. However, when I 'make' the build fails in the wacom kernel driver module section with errors like this: make[2]: Leaving directory `/home/olpc/linuxwacom-0.8.8-10/src/xdrv' Making all in 2.6.30 make[2]: Entering directory `/home/olpc/linuxwacom-0.8.8-10/src/2.6.30' Building linuxwacom drivers for 2.6 kernel. ***Note: Drivers not enabled as modules in your kernel config but requested through configure are NOT built make -C /lib/modules/2.6.31_xo1-20101119.1249.1.olpc.3781c4e5eac361a/build M=/home/olpc/linuxwacom-0.8.8-10/src/2.6.30 make[3]: Entering directory `/usr/src/kernels/2.6.31_xo1-20101119.1249.1.olpc.3781c4e5eac361a-i586' LD /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/built-in.o CC [M] /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.o In file included from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.h:12, from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.c:15: include/linux/types.h:4:23: error: asm/types.h: No such file or directory In file included from include/linux/types.h:14, from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.h:12, from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.c:15: include/linux/posix_types.h:47:29: error: asm/posix_types.h: No such file or directory In file included from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.h:12, from /home/olpc/linuxwacom-0.8.8-10/src/2.6.30/wacom_wac.c:15: include/linux/types.h:18: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__kernel_dev_t’ include/linux/types.h:21: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘dev_t’ include/linux/types.h:22: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘ino_t’ include/linux/types.h:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘mode_t’ and many more lines of same... Any help would be greatly appreciated as I was hoping to give my nieces the 10.1.3 upgrade and the working (again) wacom table for drawing (I had it working with 802). Thanks in advance, Chris P.S.

Thanks, Given that OLPC machines out there currently have broken battery information with UPower and friends, I think that the patches should be applied. Doing stuff in the EC or device-tree may be done in the future, but even after it's written debugged, it will still take some time for people to upgrade their firmware. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

In the general case in future though, it would be really useful if we could avoid having magic numbers like this in the kernel; we want them to come from as close to the hardware as possible. Given that we *have* a sane firmware on OLPC, we should be using it. -- dwmw2 ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Gerald Gerald: Though you're supposed to use keys, and I still do from my main desktop, it's convenient when you're sshing from multiple XOs or other computers to go ahead and enable password based ssh login.

In both those files, uncomment PasswordAuthentication yes and comment out PasswordAuthentication no so it looks like this: # To disable tunneled clear text passwords, change to no here! PasswordAuthentication yes #PermitEmptyPasswords no #PasswordAuthentication no Restart the ssh service. service sshd restart Now from an XO connected to the XS, you can ssh ger...@172.18.0.1 or ssh gerald@XS's hostname Enter in your password and you should be greeted with the motd! After you successfully ssh in, you can su root. Sometimes that's not root enough, though and you might have to 'sudo su -' if it says you can't do something.

Re: [Server-devel] Connecting the a Schoolserver via SSH
Anna, Thanks. I'll try this out tomorrow. I have another question for you. I was testing the server with about 12 XOs today. They all connected fine and had internet connections. But the performance seemed slow. It took several seconds for pages to load at times. Also, when I tried to have shared Activities (I opened a chat session, for example), the performance was horribly slow, and not every computer could connect. Do you have any ideas about why this might be happening and how to make it better? Thanks.

Do you have any ideas about why this might be happening and how to make it better? Thanks. Gerald The slow page load in either Firefox or Browse is usually helped quite a bit by disabling ipv6. In a (recent) Browse activity or Firefox, enter about:config in the address bar. Type ipv6 in the filter bar. The Preference Name you're looking for is network.dns.disableIPv6. Double click it to set the value to true. That usually helps page load speed quite a bit. If activities seems really slow when they're shared over the XS versus the XO-1 mesh, I don't know what that might be other than the throughput of your AP. If you suspect your XS setup, you can always connect to my test XS 0.6 running a semi-public Jabber to see if there's a difference. In fact, we've just been testing joining the XO Chat activity with regular XMPP clients like Pidgin and Gajim. Send me a private email if you'd like the URL. And that goes for anyone who's interested, not just Gerald. Anna Schoolfield Birmingham ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
