 Posted: Tue Aug 18, 2015 1:15 am Post subject: [SOLVED]wacom tablet not recognized, need rescuecd for xorg |
 |
|
I had Gentoo running nicely on my ten-year-old AMD computer. That computer stopped working and I'm trying to get Gentoo running on a newly-built Intel core i7 machine, but I'm having a couple of issues:
1. My Wacom Bamboo tablet isn't recognized (this computer is for image editing, so having the tablet work is pretty important).
2. I'm having to boot from a systemrescue"cd" on a USB key (there's no CD/DVD player on the new machine), or else I can't get to my desktop because X doesn't start.
I have the world file and portage files from the old machine, so I was able to install all the software that I had installed on the old machine, with all the same USE flags. As with the old machine, I'm running Icewm and "startx", with a mix of kde and gtk apps (kitless and gnome-free), using eudev and openrc. Unlike the old Gentoo install, on the new machine I'm using genkernel and grub2, which might be related to both issues. I wasn't able to do "grub2-mkconfig" during the initial installation. The bios is set to "legacy" for everything, but I think maybe Gentoo is trying to boot using that uefi thing, and I wasn't sure what to do during the install when it said to add modules to some conf file.
Any help getting the Wacom tablet recognized, and/or getting Gentoo to boot without having to use a rescue cd, is very much appreciated. I don't know enough about the boot process to even try to give relevant information. But here is possibly Wacom-relevant information:
"make.conf" says: | Code: | INPUT_DEVICES="evdev"
VIDEO_CARDS="intel" |
which corresponds to what the old make.conf says, except the old AMD machine had an nvidia graphics card. I've also tried various combinations of "evdev wacom mouse keyboard" for INPUT_DEVICES.
In package.use (same as the old machine) the xorg-server use flags are: "x11-base/xorg-server suid udev". Per forum advice, I added "x11-base/xorg-drivers input_devices_wacom", but it didn't help. I don't think I had "dev-libs/libwacom" installed on the old machine, but I think maybe the "input_devices_wacom" use flag pulls it in? Or maybe putting "wacom" in make.conf in INPUT_DEVICES?
When I unplug and plug in the Wacom tablet, dmesg | tail says: | Code: | [ 2967.262692] usb 3-4.1: USB disconnect, device number 5
[ 2971.947649] usb 3-4.1: new full-speed USB device number 6 using xhci_hcd

lsusb says: | Code: | | Bus 003 Device 006: ID 056a:00de Wacom Co., Ltd CTH-470 [Bamboo Fun Pen & Touch] |
"xsetwacom --list devices" doesn't list anything. Nor does "modprobe wacom" do anything (not sure if there is supposed to be any terminal output).
Thanks very much for any help,
Elle

I used the rescue cd burned to a USB key to install Gentoo. I built this machine, so Windows has never been installed and dual-booting is not a concern.
My first attempt at installing Gentoo on the new machine failed because after booting up, the minimal Gentoo install "cd on a usb key" couldn't find the install files to actually perform the installation (there is no CD/DVD device in the machine, so installing from an actual CD is not an option). I did manage to install OpenSuse, and then removed OpenSuse and installed Debian and removed Debian. After the installs, they both booted successfully from the ssd. They didn't require booting from a rescue "cd on a usb key" in order to get to the desktop, and the Wacom tablet worked in both OpenSuse and Debian. So clearly I'm doing something wrong with the Gentoo install.
When starting Gentoo using the rescue "cd", the background is blue, which apparently means the rescue "cd" is starting the OS in legacy bios mode (https://forums.gentoo.org/viewtopic-t-1026806.html, 3rd post). The bios on the motherboard is set to boot in legacy mode. The operating system is set to "other", which apparently is the way to disable secure boot on the Asus Z97-A motherboard.
The new Gentoo operating system is on a nominally 250GB Samsung EVO 850 sdd (which apparently wasn't the best choice of ssd because of trim issues, but that's not the issue at hand). After starting Gentoo from the rescue cd, and then running fdisk -l from within Gentoo, here's what is reported: | Code: | fdisk -l

"Swap" is located on a second drive, though with 32GB RAM, I'm not sure if swap space is really necessary.
Per advice from https://wiki.gentoo.org/wiki/GRUB2_Quick_Start, I put GRUB_PLATFORMS="pc" in make.conf, but it didn't make any difference.
When I try to start Gentoo directly, without using the rescue "cd" to boot the system, "startx" fails. The Xorg log says | Code: | [ 656.611]

I'm pretty sure the problem started during the initial installation from the rescue "cd". Following the handbook wasn't exactly easy. Neither links nor lynx was installed on the rescue cd, but wget worked. For some reason I got kicked out of the chroot twice, and had to watch very carefully to make sure I actually was inside the chroot when running commands. The real problem started when it was time to configure a boot loader. This step wouldn't work: | Code: | | grub2-mkconfig -o /boot/grub/grub.cfg |
I believe the error message said something about not being able to find the canonical path, and complained about the boot partition being write-only. So I booted the new Gentoo install from the rescue "cd" and ran the grub2-mkconfig command.
Any help with resolving these issues, and especially with getting the Wacom tablet recognized, would be greatly appreciated. Having to start Gentoo using the rescue CD is a minor annoyance, but not being able to use the Wacom tablet is a show-stopper. I think resolving the "won't start without the rescue cd" issue will probably also resolve the Wacom tablet issue.

The very nice people on Gentoo IRC told me how to boot from disk instead of having to boot from the rescue"cd". The solution was to put this line in /etc/default/grub: | Code: | | GRUB_CMDLINE_LINUX="i915.modeset=1" |
They also told me how to get the Wacom tablet working. The solution was to put INPUT_DEVICES="evdev wacom" in make.conf, reinstall the xorg drivers (emerge -1a xorg-drivers), then run genkernel using the following command: | Code: | | genkernel --menuconfig all |
and then hit "/", search for hid_wacom, and activate it, and save without changing the default file name.
I've run various flavors of Linux since 2007, and Gentoo is by far the best, imho. I love being able to run all my qt/kde apps completely kitless and being able to avoid systemd and gnome libraries. But I've never felt comfortable when compiling a custom kernel because I don't understand most of the options. So on the new machine I decided to go with genkernel. But I probably could have avoided some angst about getting this new machine up and running if I had just gone ahead and compiled a custom kernel.
Best,
